P = 2l + 2w
P = 2(x + 3) + 2(7)
P = 2(x) + 2(3) + 14
P = 2x + 6 + 14
P = 2x + 20
A = lw
A= 7(x + 3)
A = 7(x) + 7(3)
A = 7x + 21
The initial cost is $45. To determine the increase, you need to follow two steps.
First you have to find what 7% of the original $45 is. This will tell us how much the cost will increase by.
To find 7% of $45, you need to multiply .07 x 45 = 3.15
This tells us that 7% of $45 = $3.15
Next, you have to add the increase to the original cost. This will be the new monthly cost.
$45 + $3.15 = $48.15
