Question

Each member of the school chess team receives a chess set and clock. The total cost of these items for 5 members is $125. Jenna knows that a chess set costs $10, but she does not know how much a clock costs. She sets up the equation below to solve for the cost of a clock, represented in her equation by x.

5(x + 10) = 125

What is the value of x?

A.
$15

B.
$23

C.
$25

D.
$35

Answer 1

5(x + 10) = 125
x + 10 = 25 (divide both sides by 5)
x = 15

Answer: A ($15)
