Emily saved some of her school pocket money for 3 days. She saved $2 on the first day. For the remaining 2 days, she saved $0.80 more than the previous day.
- How much money did she save in 3 days?
- Emily then spent all her savings on 4 identical pens. How much did each pen cost?
(a)
Amount that Emily saved on the first day = $2
Amount that Emily saved on the second day = $2 + $0.80
Amount that Emily saved on the third day = $2 + $0.80 + $0.80
Total amount the Emily saved in 3 days
= 3 x 2 + 3 x 0.80
= 6 + 2.40
= $8.40
(b)
Cost of each pen
= 8.40 ÷ 4
= $2.10
Answer(s): (a) $8.40; (b) $2.10
