Norah bought a guitar that was on sale for 15% off the regular price of $200. The total cost included 8% sales tax. What was the total cost?

A)$186.00

B)$183.60

C)$178.00

D)$176.80

Answers

Answer 1
.15 x 200= 30
200-30= 170
.08 x 170 = 13.6
170+13.6= 183.60

The answer is B.
Answer 2

A percentage is a number or ratio that represents a fraction of 100. 

The total cost of the guitar including sales tax and the offer discount is $186.

What is percentage?

A percentage is a number or ratio that represents a fraction of 100. 

We have,

The regular price of the guitar = $200

Sales tax = 8%

Cost of sales tax = 8/100 x 200 = $16

Offer rate = 15%

Offer = 15/100 x 200 = $30

The total cost of the guitar:

= (200 - 30) + 16

= 170 + 16

= $186

Thus,

The total cost of the guitar including sales tax and the offer discount is $186.

Option A is the correct answer.

Wednesday morning, the temperature was −12 ∘F. By the afternoon, the temperature was 23 ∘F. Write and then evaluate a subtraction expression to determine the number of degrees of change in temperature between the morning and the afternoon.

Answers

23-12=11 11 degrees should be the answer

The change in temperature between the morning and the afternoon would be 35° F.

What is the Subtraction operation?

Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.

We have been given that Wednesday morning, the temperature was −12° F. By the afternoon, the temperature was 23° F.

We have to determine the change in temperature between the morning and the afternoon

As per the given question,

Here, final temperature = 23° F and initial temperature = −12° F

The change in temperature = final temperature -  initial temperature

The change in temperature =  23° F - ( -12° F )

Apply the subtraction operation,

The change in temperature =  23° F + 12° F

The change in temperature =  35° F

Hence, the change in temperature between the morning and the afternoon would be 35° F.

how do you change y – 5 = - (x – 1) into slope intercept form?

Answers

Answer:

y = -x + 6

Step-by-step explanation:

Slope intercept form is y = mx + b.

So distribute the negative sign on the right side to get:

y - 5 = -x +1

Then  add the 5 on the left side to both of the sides to get y alone, then you will get:

y = -x +6

That is in slope intercept form.

At a grocery store, you can buy a 20-ounce of peanuts for $3.59, or you can buy a one-pound (16 ounces) package for $2.59. Why is the one-pound package the better deal? Explain your answer by talking about unit rates.

Answers

Answer- The one pound package is a better deal because it costs 32 cents per ounce rather than the 20 oz, which charged 45 cents per oz.

Explanation- let’s convert all units to ONE OUNCE. 3.59/20(oz)= 0.45, do 45 cents per ounce for the first. For the second, we know that one pound is 8 oz so divide 2.59 by 8 and you get 32 cents per oz. We know that if we are getting 8 oz for 32 cents per ounce, it is the better deal rather than 45 cents per oz.
