In a rectangle, the perimeter is 102 inches. The width of the rectangle is 9 inch more than half the
Harrizon [31]

perimeter = 2width + 2 length

102 = 2(x+9) + 2x

102 = 2x + 18 +2x

102 = 4x +18

84 = 4x

21 = x

Length = x = 21 inches

Width = x + 9 = 21 + 9 = 30 inches

tatuchka [14]
This question shows you how to determine the amount of money Mr. Leonard makes in 4 weeks.  It takes his total salary, divides it by 52 (there are 52 weeks in a year), then multiplies it by 4 (you need 4 weeks worth of pay). 

This amount is shown as $6769.24.

He must pay the agency 22% of this, so change 22% to 0.22 and multiply it by the amount he makes in 4 weeks.

0.22 x 6769.24 = $1489.23

Mr. Leonard must pay the agency $1489.23 after the first 4 weeks.
