Question

Susan may pays $2.80 for a gallon of sister, who lives in another city pays $2.25 for a gallon of milk. If both families use 3 gallons of milk per week, how much more does susan pay for milk in a year? ( assume 52 weeks in a year.)

Answer 1

Susan pays $0.55 more per gallon of milk compared to her sister, which results in $1.65 more each week. Over a year, Susan pays $85.80 more for milk.

Step-by-step explanation:

The question asks us to calculate how much more Susan pays for milk compared to her sister on a yearly basis, provided that both consume 3 gallons of milk each week.

First, we need to find the difference in price per gallon of milk between Susan and her sister. Susan pays $2.80 per gallon whereas her sister pays $2.25. The difference per gallon is $2.80 - $2.25 = $0.55. Next, to find out how much more Susan pays weekly, we multiply the difference in price per gallon by the number of gallons they use per week. So, $0.55 per gallon x 3 gallons per week = $1.65 more per week. Finally, to find the annual difference, we multiply the weekly difference by the number of weeks in a year. Therefore, $1.65 more per week x 52 weeks in a year = $85.80 more per year.
