Explanation & Answer

Question 15.
Assuming that the amount of gas bought during refilling is equal to full tank of each vehicle and by 285 miles each vehicle will have used up its full tank, then:
Monica,s expenditure= (1800/285)x22.8x3.49=$504.33
Matt's expenditure=(1800/285)x9.5x3.49=$209.4
the total expenditure for the trip=504.33+209.4=$713.73
Question 16.
Monica's additional expenditure=(22.8/285)x300x100% = $24
Matt's additional expenditure=(9.5/285)x300x25% = $2.5
the total new cost is: Monica=$ 528.33
Matt's = $ 211.9
Total=%28.33+211.9= $ 740.23
