Question

Stephen is paid $25 to mow a lawn. This amount is $4 less than twice the amount he received when he first began mowing. Use the model to determine x, the amount Stephen received when he first began mowing.

Answer 1

$14.5

Explanation:

Given

`Amount = 25`

Required

Determine the amount paid to him initially (x)

Analyzing the question, one after the other:

4 less than twice the amount: 2x - 4

Hence;

`Amount = 2x - 4`

Substitute 25 for Amount

`25 = 2x - 4`

Add 4 to both sides

`4 + 25 = 2x - 4 + 4`

`29 = 2x`

Divide both sides by 2

`29/2 = 2x/2`

`29/2 = x`

`14.5 = x`

`x = 14.5`

Hence, he received $14.5 when he first started
