Jean paid $15 for one hoodie and one shirt. The shirt costs 4 times as much as the hoodie.
- How much did the hoodie cost?
- How much more did the shirt cost than the hoodie?
(a)
Cost of the hoodie = 1 u
Cost of the shirt = 4 u
Total cost of the hoodie and the shirt
= 1 u + 4 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Cost of the hoodie = $3
(b)
Cost of the shirt more than the hoodie
= 4 u - 1 u
= 3 u
= 3 x 3
= $9
Answer(s): (a) $3; (b) $9
