Question

Which equation below and solution for x does the model represent?

A) 2x + 2x = 85, x=42.50

B) 4 + x = 85, x=21.00

C) x + x + x = 85, x=21.00

D) 4x = 85, x=21.25

Answer 1

Option D

Explanation:

Cost of 4 shirts all together = $85

Model given in the picture attached will be,

x + x + x + x = 85

4x = 85

`(4x)/(4)=(85)/(4)`

x = 21.25

Therefore, Option D will be the correct option.
