The variable 'a' represents how much Arthur saves. Because D'John saves $8 per week (7 days), he saves $56. Arthur saves four times more than D'John so $56*4 equals Arthur's total savings for the week; $224. a=$8(7)*4 a=$56*4 a=$224

The glass part of a window is 32 1/2 inches wide. Including the frame on the left and right sides, the total width is 42 inches.

The glass part of the frame is an illustration of fractions

The width of each side of the frame is 5 1/4 inches

<h3>How to determine the width of each side?</h3>

The given parameters are:

Total width = 42 inches
Glass part = 32 1/2 inches

Represent the width of each side with x.

So, we have:

Glass part + 2x = Total width

Substitute known values

31 1/2 + 2x = 42

Subtract 31 1/2 from both sides

2x = 10 1/2

Divide both sides by 2

x = 5 1/4

Hence, the width of each side of the frame is 5 1/4 inches
