Select an equation to solve the problem. Then solve. Joaquin is saving $369 to buy a surf board. He saved $9 each week for 11 weeks. He wants to buy the surf board in 9 more weeks. How much does Joaquin need to save each week? Let m be how much money Joaquin needs to save each week. Select an equation to solve the problem. ? Solve the equation. M = Answer the question. Joaquin needs to save $ each week.

Joaquin needs to save $30 each week.

Step-by-step explanation:

Total money required for buying a surf board = $369

Money saved every week for first 11 weeks = $9

Total money saved in first 11 weeks = 11 9 = $99

Joaquin wants to buy the surf board in 9 more weeks.

To find:

Money to be saved each week for the next 9 weeks so that the surf board can be bought?
