A family can spend at most $25 at Fun Zone. It costs $10 an hour for trampolines and $5 an hour for the pool. The family can stay less than 4 hours.

Select the point that represents a solution.

• (1, 3); 1 hour on the trampolines and 3 hours in the pool

• (4, 0); 4 hours on the trampolines and no hours in the pool

• (1.5, 2); 1.5 hours on the trampoline and 2 hours in the pool
