Esther paid $42 for one sweater and one hoodie. The hoodie costs 6 times as much as the sweater.
- How much did the sweater cost?
- How much more did the hoodie cost than the sweater?
(a)
Cost of the sweater = 1 u
Cost of the hoodie = 6 u
Total cost of the sweater and the hoodie
= 1 u + 6 u
= 7 u
7 u = 42
1 u = 42 ÷ 7 = 6
Cost of the sweater = $6
(b)
Cost of the hoodie more than the sweater
= 6 u - 1 u
= 5 u
= 5 x 6
= $30
Answer(s): (a) $6; (b) $30
