4. If Sam goes swimming 4 times he pays:
With early pay: $50
With deposit plus: $25 + ($3 x 4 days) = 25 + 12 = $37
With daily pay: ($7 x 4 days) = $28
Best value in this case is daily pay
5. If Sam goes swimming 7 times he pays:
Early pay: $50
With deposit plus: $25 + ($3 x 8 days) = $25 + 24 = $49
With daily pay: ($7 x 8 days) = $56
In this case, deposit plus is the best value
6. If Sam goes swimming 12 times, he pays:

With deposit plus: $25 + ($3 x 12 days) = $25 + 36 = $61
With daily pay: ($7 x 12 days) = $84
