C. $2.64
D. $2.72
E. $2.90
Amount Sally will have to pay this week = [26.40/1.65]*1.82 = 16*1.82 = $29.12
Amount Sally will have to pay = 29.12 - 26.40 = $2.72
The correct answer: D
Hope this helps!

Since $26.40 bought 26.40/1.65 = 16 gallons last week, and this week she has to pay 1.82 - 1.65 = $0.17 more per gallon, she has to pay 16 x 0.17 = $2.72 more this week for the same amount of gasoline.BTGmoderatorDC wrote:The price of gasoline at a service station increased from $1.65 per gallon last week to $1.82 per gallon this week.
