Kia purchased 3 pounds of grapes and spent $11.63 on other items. She spent a total of $20. She used the following steps to find

Maurinko [17]

3x + 11.63 = 20
3x + 11.63 - 11.63 = 20 - 11.63
3x = 8.37

by subtracting the 11.63 from both sides, this tells us how much the grapes cost....not per lb., but for the total of all the grapes.
