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
Anettt [7]
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.
