Ok well let's work this out step by step. The store sells 7 IBs of trail mix AND jelly beans = $53. For 5 IBs of JUST trail mix, and 3 IBs of JUST jelly bean = $25. What would you do first?

add? i have no clue

OpenStudy (anonymous):

Well, 5 and 3 make 7. So in all, wouldn't it all add up to $53?

OpenStudy (anonymous):
