$162 A 5-day stay does not cost half as much as a 10-day stay
Work Step by Step
a) Relate: The total cost is \$15 dollars per day plus \$12 for the bath. Define: Let C = Total cost. Let d= the number of days. Write: $C=15d +12$ For 10 days: $C=15(10) +12=\$162$ b) For 5 days: $C=15(5) +12=\$87$ A 5-day stay does not cost half as much as a 10-day stay.
