Cindy saved some of her school pocket money for 4 days. She saved $5 on the first day. For the remaining 3 days, she saved $0.70 more than the previous day.
- How much money did she save in 4 days?
- Cindy then spent all her savings on 2 identical staplers. How much did each stapler cost?
(a)
Amount that Cindy saved on the first day = $5
Amount that Cindy saved on the second day = $5 + $0.70
Amount that Cindy saved on the third day = $5 + $0.70 + $0.70
Amount that Cindy saved on the fourth day = $5 + $0.70 + $0.70 + $0.70
Total amount the Cindy saved in 4 days
= 4 x 5 + 6 x 0.70
= 20 + 4.20
= $24.20
(b)
Cost of each stapler
= 24.20 ÷ 2
= $12.10
Answer(s): (a) $24.20; (b) $12.10
