Shirt = $45
Belt = $78
Total spent = $873
Group 1 shirt and 1 belt together = $45 + $78 = $123
Remove the 3 extra shirts from the total so you will have same number of shirts and belts, $873 - ($45 x 3) = $738
No. of sets = $738 / $123 = 6
(a) No. of belts = 6
(b) total shirts = 9 x $45 = $405
(Checking: shirts = $405, belts = $78 x 6 = $468, total = $873)
