How many weeks will it take Justin to save $133 if he saves $9.50/wk? Derive a complete equation to model the problem. Use w to represent the unknown value.
Let w be the unknown number of weeks. The total amount that Justin saves is the product of the amount he saves every week and the number of weeks. That is, ($9.50) x w = $133 Rearranging the equation for w, w = $133 / $9.50 Thus, the answer is 14.
