Answer:
a. hourly rate
b. the cost before the tax
c. tax rate
d. tax amount
e. 299.6
Step-by-step explanation:
When you look at the formula, since h represents the number of hours and it is multiplied with 80, you can tell that 80 is the hourly rate. This is how you would calculate the cost if there was no tax. Also, you can see that it is also multiplied with 0.07, that implies 0.07 is the tax rate and 0.07(80h) is the tax amount.
Since h represents the number of hours in the given formula:
→ 0.07(80h)+80h = 0.07(80(3.5)) + 80(3.5) = 19.6 + 280 = 299.6
