Part A is $650. Part B is 400+0.05s=1350, and part C is $19,000. For part A, it is $400+ 5% of total sales. So, it would be 400+5% times 5000 (which is the total sales of last week). Turn the 5% into a decimal so 400+0.05 times 5000. Then it would be 400+250, which is 650. For part B, it would be $400 per week and 5% of total sales for that week. This as an equation would be $400+0.05 times s=$1350. We can put 0.05 and the variable s together. So, it would then be 400+0.05s=$1350. This is the equation. For part C, we have to solve the equation in part B. $400+0.05s=$1350. Subtract 400 from 400 and 1350. This now makes the equation 0.05s= $950. Divide both sides by 0.05 and you get 19,000.
Answer:
30
Step-by-step explanation:
Set up the proportion y=kx k equals y over x
y=2x
y=30 if x is 15
(3,452 * 2) = round trip = 6,904.
6,904 * 3 = total distance = 20,712.
Therefore, the final answer is 20,712 miles.
