Mary's car is 10 years old and has a problem. The repair man indicates that it will cost her $1200.00 to repair her car. She can purchase a different, more efficient car for $4,500.00. Her present car averages about $2,000.00 per year for gas while the new car would average about $1,500.00 per year. Find the number of years for when the total cost of repair would equal the total cost of replacement.
Answer:
6 years 6 monthsStep-by-step explanation:
given data
let the number of year be x
le the total cost b y
for the older car
cost of repair $1200
cost of gas $2,000.00 per year
the cost for using the old car is
y=1200+2000x-----------1
for the new car
cost of $4500
cost of gas $1,500.00 per year
y=4500+1500x-----------2
equating 1 and 2 we have
1200+2000x=4500+1500x
solving for x
1200-4500=1500x-2000x
-3300=-500x
x=3300/500
x=6.6
The number of years is 6 years 6 months
Graph a line that contains the point (4,3) and has a slope of 1/2
Answer:
Equation is y = 1/2x + 1
Step-by-step explanation:
First off we know the slope, it is 1/2, so that is done already. Now we just need the y-intercept. In order to cross (4, 3), in needs to have a y-intercept of 1. So the equation is y = 1/2x + 1. I hope this helps, and I hope it's not wrong, but I don't think it is.

Which equation has infinitely many solutions?
1. 12 + 4x = 6x + 10 – 2x
2. 5x + 14 – 4x = 23 + x – 9
3. X + 9 – 0.8x = 5.2x + 17 - 8
4. 4x – 2x = 20
Mario is the manager at a local store. He has budgeted $1600 for the wages of the cahiers for the week. If each cashier make $8.75 an hour, how many total hours can the cashiers work that week?
Answer:
182 hours
Step-by-step explanation:
In this scenario, the total would be $1600 which is the maximum amount that can be wasted. The only variable in this scenario is the number of hours that the cashier can work. Therefore we can use the following formula to calculate the maximum number of hours the cashier can actually work (h) before going over the total limit.
8.75h = 1600 ... divide each side by 8.75
h = 182.85
Therefore, we see that the total amount of hours equals 182.85 but since we are counting hours then the answer would be 182 hours because if the cashiers work 183 hours there won't be enough money budgeted to pay them.
A convenience store sell pre-paid mobile phones. It purchases them for $12 each and uses a mark up rate of 250%. What is the mark-up amount for the phones? What is the retail price of the phones after the mark up?
Answer:
The convenience store has a markup amount of $30 on the pre-paid mobile phones and the retail price is $42
Step-by-step explanation:
The purchase price of the pre-paid mobile phones is $12.
The convenience store uses a markup rate of 250%.
The markup amount is:
250 * 12 / 100 = 30
The retail price is the purchase price plus the markup amount:
Retail price = $12 + $30 = $42
The convenience store has a markup amount of $30 on the pre-paid mobile phones and the retail price is $42

15% of what number is 24?
O A) 36
OB) 150
OC) 160
OD) 180
Answer:
160
Step-by-step explanation:
We have, 15% × x = 24
or,
15
100
× x = 24
Multiplying both sides by 100 and dividing both sides by 15,
we have x = 24 ×
100
15
x = 160
If you are using a calculator, simply enter 24×100÷15, which will give you the answer.
Answer:
C) 160
Step-by-step explanation:
Let the number be x
15% of x = 15/100 * x
15/100 * x = 24
x = 24*100 / 15
x = 160

Yasmine finds the absolute value of –655. Which expression represents this value? 0 + (negative 655) 0 minus (negative 655) (negative 655) + 655 (negative 655) minus 655
Answer:
0 minus (negative 655)Step-by-step explanation:
Absolute of a number is the positive value of such number. for example, the absolute value of -7 is 7.
If Yasmine finds the absolute value of -655, then her equivalent value must return a positive answer.

Mauricio y Peter tienen una banda y componen 6 canciones en 15 días. Si llaman a su amigo Anderson para que les ayude durante 5 días, ¿Cuántas canciones compondrán?
Responder:
2 canciones
Explicación paso a paso:
Si la cantidad de canciones compuestas en 15 días es de 6 canciones, si Anderson se une a ellos para ayudar durante 5 días, el número total de canciones que producirán en 5 días se calculará como se muestra:
15 días = 6 canciones
5 días = x canciones
Cruz multiplicar
15 días * x = 5 días * 6 canciones
15 veces = 30
Dividir entre 15
15 veces / 15 = 30/15
x = 2
Por lo tanto, compondrán 2 canciones si Anderson les ayuda durante 5 días.
