Shannon saved some of her school pocket money for 5 days. She saved $8 on the first day. For the remaining 4 days, she saved $0.70 more than the previous day.
- How much money did she save in 5 days?
- Shannon then spent all her savings on 2 identical staplers. How much did each stapler cost?
(a)
Amount that Shannon saved on the first day = $8
Amount that Shannon saved on the second day = $8 + $0.70
Amount that Shannon saved on the third day = $8 + $0.70 + $0.70
Amount that Shannon saved on the fourth day = $8 + $0.70 + $0.70 + $0.70
Amount that Shannon saved on the fifth day = $8 + $0.70 + $0.70 + $0.70 + $0.70
Total amount the Shannon saved in 5 days
= 5 x 8 + 10 x 0.70
= 40 + 7
= $47
(b)
Cost of each stapler
= 47 ÷ 2
= $23.50
Answer(s): (a) $47; (b) $23.50
