Your friend was trying to complete this problem: there is a sale at the store and you have $50 to spend. jeans cost $12 and shirts cost $8 if you buy 2 pairs of jeans and 3 shirts, will they have any money left over? if so how much? their no they will not have any money left because 2 pairs of jeans would cost $26 and 3 shirts would cost $24 and 26+24=50 so they would spend exactly the right amount. explain their mistake! what did they do wrong? what should their answer have been?
