Question

Steven has $25 dollars. He needs to set aside $10.00 to pay for his lunch next week. If peanuts cost $0.38 per package including tax, at most how many packages can Steve buy?

Answer 1

39 packages.

Because he sets aside 10, he has $15 left.
15 divided by $0.38 = 39.4736, however he cannot but a fraction of a package so you round down to 39.
