Suppose a little girl likes peanut butter and jelly sandwiches with exactly 2T of jelly and 1T of peanut butter.Suppose further that her mom agrees to make sandwiches to those exact specifications and the price of peanut butter is $.25/T and the price of jelly is $.10/T.If she has $1.80 to spend on peanut butter and jelly ingredients (ignore the bread)in a week,how many sandwiches will she make?

Question

Quizplus · Accepted Answer

Each sandwich requires 2T of jelly and 1T of peanut butter, so the ingredients cost for one sandwich is:
2T jelly * $0.10/T = $0.20
1T peanut butter * $0.25/T = $0.25
Total cost per sandwich = $0.20 + $0.25 = $0.45

If she has $1.80 to spend in a week, she can make:
$1.80 / $0.45 per sandwich = 4 sandwiches

Therefore, the best choice is C) 4.
