Answer:
A) $29.68
B) $5.60
Step-by-step explanation:
<u>Part A Explanation)</u>
To find the total cost including tax, you must multiply the total cost by .06 because .06 out of 1 is 6%. <em>Quick explanation on percentages.</em>
<u><em>DO NOT FORGET TO ADD THE TOTAL COST</em></u>
28.00 + (28.00 * .06) = 29.68
<u>Part B Explanation)</u>
This is asking only for the tip, not including the total cost. However, we need the total cost to calculate the tip.
28.00 * .20 = 5.6
<em>.20 out of 1 is 20%</em>
Represent the number of days by x. With this representation, the variable cost of the rental is 31.67x. The total cost is the sum of the fixed and variable costs. This value should not be more than $500. The equation below shows the relationship.
130 + 31.67x ≤ 500
Solving for x gives x ≤ 11.68
Thus, the maximum number of days to rent the car is only 11 days.
