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

Answer:

$14.5

Step-by-step 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
