Jaslyn saved some of her school pocket money for 3 days. She saved $2 on the first day. For the remaining 2 days, she saved $0.20 more than the previous day.
- How much money did she save in 3 days?
- Jaslyn then spent all her savings on 6 identical files. How much did each file cost?
(a)
Amount that Jaslyn saved on the first day = $2
Amount that Jaslyn saved on the second day = $2 + $0.20
Amount that Jaslyn saved on the third day = $2 + $0.20 + $0.20
Total amount the Jaslyn saved in 3 days
= 3 x 2 + 3 x 0.20
= 6 + 0.60
= $6.60
(b)
Cost of each file
= 6.60 ÷ 6
= $1.10
Answer(s): (a) $6.60; (b) $1.10
