For every $3 Mac saves to buy a bicycle, his dad will give him an additional $5 to put
toward the purchase of the bike. How much will Max have to save before he can buy a $120 bicycle?

Let's solve this step by step:

1. For every $3 that Mac saves, his dad contributes an additional $5.
   - Therefore, for every $3 Mac saves, the total amount toward the bicycle becomes $3 + $5 = $8.

2. Let $ x $ be the amount Mac has to save.
   - The total amount Mac and his dad will have together toward the bicycle is $ \frac{8}{3}x $.

3. Since the total price of the bicycle is $120, we set up the equation:
   \[
   \frac{8}{3}x = 120
   \]

4. Solving for $ x $:
   \[
   x = \frac{120 \times 3}{8} = \frac{360}{8} = 45
   \]

Thus, Mac will have to save **$45** in order to buy the $120 bicycle.
