To determine how many weeks it will take Justin to save up for the game, we can follow these steps:
-
Calculate how much more money he needs to save:
- The cost of the game is $135.
- Justin currently has $10.
- Therefore, he needs an additional: \[ 135 - 10 = 125 \text{ dollars} \]
-
Determine how much he saves each week:
- Justin plans to save $25 each week.
-
Calculate the number of weeks required to save the additional $125: \[ \text{Number of weeks} = \frac{125 \text{ dollars}}{25 \text{ dollars/week}} = 5 \text{ weeks} \]
So, Justin needs 5 weeks to save enough money to buy the game.
