Answer 1

To determine how many weeks it will take Jackson to save enough money to buy the electric dirt bike, we first need to find out how much more money he needs to save.

1. Calculate how much more money Jackson needs:
\[
\text{Cost of the bike} - \text{Amount saved} = 459 - 174 = 285
\]

2. Calculate how much Jackson saves each week:
\[
\text{Weekly saving} = 15 + 4 = 19
\]

3. Calculate the number of weeks needed to save the remaining amount:
\[
\text{Number of weeks} = \frac{\text{Amount needed}}{\text{Weekly saving}} = \frac{285}{19}
\]

4. Performing the division:
\[
285 \div 19 \approx 15
\]

Jackson will need approximately 15 weeks to save enough money to buy the bike.

Thus, the answer is **15 weeks**.
