Bob buys eggs and potatoes at a store.
• He pays a total of $25.92.
• He pays $2.57 for the eggs.
• He buys 5 bags of potatoes that each cost the same amount, Which equation can be used to determine the cost, x, of each bag of potatoes?

a. X = (25.92 - 2.57) = 5

b. x = 25.92 = 5 + 2.57

c. X = (25.92 +2.57) = 5

d. x = 25.92 - 5 -2.57
