Sabrina paid $102 for a windbreaker and a necklace. The necklace cost five times as much as the windbreaker.
- Find the cost of the windbreaker.
- Find the cost of the necklace.
(a)
Cost of 1 necklace = 5 u
Cost of 1 windbreaker = 1 u
Total cost of 1 necklace and 1 windbreaker
= 5 u + 1 u
= 6 u
6 u = $102
1 u = 102 ÷ 6 = 17
Cost of the windbreaker
= 1 u
= $17
(b)
Cost of the necklace
= 5 u
= 5 x 17
= $85
Answer(s): (a) $17; (b) $85
