Answer: 1.134
Step-by-step explanation:
(after price-initial price\initial price)100=percent of change
the initial price = 72
(a week later)after price = 87
87-72=15
15/72=.20833333333
.20833333333*100= 20.833333333
the percent of change of initial price of $72 and the after price of $87= 20.833333333= 2.08%

the area=length times width=16 times 2=32 square inches
32 times amount charged per square inch=32 times 18=576 cents
costs $5.76
