Tony had an equal number of cranberry bars and walnut bars. He gave away 66 cranberry bars, he had 4 times as many walnut bars as cranberry bars left. How many bars did he have at first?
4c-264=c (because c=w)
c=88 cranberry bars
w=88 walnut bars
88+88=176 bars at first
check: 88-66=22 and 88 is 4 times 22
