Question

1 Using your answer from #5 above, what would the total cost be to rent a vehicle for a week long trip (7 days)? A $450 B $750 C $350 D $1050

Answer 1

The expression c=50d+100 represents the relationship between the total cost (c) for renting a car given a determined number of days (d).

If you are going to rent a car for d=7 days, to determine the cost you have to replace that value in the expression:

c=50d+100

c=50*7+100

c=350+100

c=450
