Answer:
- $ 9.91
Explanation:
The amount that Frank paid on his last credit card bill shows how piecewise functions work.
Taking into account that:
- 1.5 percent = 1.5/100 = 0.015,
- 1 percent = 1 / 100 = 0.01, and
- 0.015 × 500 = 7.50,
You can model the amount paid using the piecewise function p(x):
Thus, your calculation is:
- x = $741.23
- p(x) = $7.50 + $ 0.01 × (741.23 - 500) = $ 9.91
