Julie saved some of her school pocket money for 3 days. She saved $11 on the first day. For the remaining 2 days, she saved $0.90 more than the previous day.
- How much money did she save in 3 days?
- Julie then spent all her savings on 7 identical staplers. How much did each stapler cost?
(a)
Amount that Julie saved on the first day = $11
Amount that Julie saved on the second day = $11 + $0.90
Amount that Julie saved on the third day = $11 + $0.90 + $0.90
Total amount the Julie saved in 3 days
= 3 x 11 + 3 x 0.90
= 33 + 2.70
= $35.70
(b)
Cost of each stapler
= 35.70 ÷ 7
= $5.10
Answer(s): (a) $35.70; (b) $5.10
