Answer:
0.88%y + 0.03%
Step-by-step explanation:
if it's 12% then: she's actually paid 88% with a tax of 3%.
5^7 = 5 × 5 × 5 × 5 × 5 × 5 × 5 = 78,125
5^-9 = 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 = 0.000000512
5^-5 = 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 = 0.00032
78,125 × 0.000000512 × 0.00032 = 0.0000128
Answer: 0.0000128 or 1.28 x 10^-5
