The school decided to add 20% to the gym budget. In a normal month, they could buy 15 dodgeballs for $5 each if they spent the entire budget on that. If they only buy softballs instead, which cost $9 each, how many can they buy with the new budget?
Think hard. Detailed solution:
10
The old budget was $75 because 15 x 5 = 75.

They are adding $15 to the budget because 75 x.

2 = 15.

The new budget is $90 because 75 + 15 = 90.

They can buy 10 softballs on the new budget because 90 / 9 = 10.

The answer: 10
