Since Brandon and Howard bought the same items at the same price, the difference in the amounts they had remains unchanged at first and in the end.
5 u - 1 u = 122 - 98
4 u = 24
1 u = 24 ÷ 4 = 6
Cost of 1 hoodie = 3 p
Cost of 1 skirt = 1 p
Total cost of 1 hoodie and 1 skirt
= 3 p + 1 p
= 4 p
4 p = 98 - 6
4 p = 92
1 p = 92 ÷ 4 = 23
Difference in the cost between the hoodie and the skirt
= 3 p - 1 p
= 2 p
= 2 x 23
= $46
Answer(s): $46
