Question

D'John saves $8 per week. Arthur saves 4 times the amount D'John saves in the same week. Write an equation that shows how to find the amount "a" Arthur saves. Then solve the equation

Answer 1

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
