A keyboard that costs $400 is marked down 10% for a sale. What is the total savings? What is the new price of the keyboard?

Answers

Answer 1

Answer:

The total savings is $40 and the new price is $360

Step-by-step explanation:

Multiply 400 by .10 and you get the savings, $40.

Then subtract 400 by 40 and you get the new price.

Answer 2

Answer:

Step-by-step explanation:

400*0.10=40

400-40 because 40 is the savings and 400 is the total price

400-40= $360 is the new price

Monique son just turned 2 years old and is 34 inches tall. Monique heard that the average boy will grow approximately 2 5/8 inches per year until the age of 15.

Part A: Write an equation that represents how old Monique son will be when he is 50 inches tall. ( let x represent the amount of year since age 2)

Part B: How old will Monique son be when he is 50 inches tall.

Answers

Answer:

The equation that represents the height as a function of the time is:

f(x) = 34 + 2.625x, where x represent the amount of year since age 2

We need to find x such that f(x) = 50 that is:

34 + 2.625x = 50

x = 6 years rounded to integer

6 years after the age of 2 is 2 + 6 = 8 years.

Monique's son will be 8 years old and 50 inches tall.
