Here's one way to approach the problem. There's actually multiple ways to solve it.
1. Figure out what 1% of $12.00 is. You do that by moving the decimal point 2 places to the left. That would be $0.12. Multiply $0.12 by 7 to figure out what 7% is... that would be $0.84. The student would pay $0.84 in tax. |
