Answer:
Step-by-step explanation:
In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440
You need to solve the equation.
20/440 = N · 440/440
0.045 repeating = N
Rounded, the sales tax rate would be 4.5%
