Emily saved some of her school pocket money for 4 days. She saved $6 on the first day. For the remaining 3 days, she saved $0.40 more than the previous day.
- How much money did she save in 4 days?
- Emily then spent all her savings on 6 identical pens. How much did each pen cost?
(a)
Amount that Emily saved on the first day = $6
Amount that Emily saved on the second day = $6 + $0.40
Amount that Emily saved on the third day = $6 + $0.40 + $0.40
Amount that Emily saved on the fourth day = $6 + $0.40 + $0.40 + $0.40
Total amount the Emily saved in 4 days
= 4 x 6 + 6 x 0.40
= 24 + 2.40
= $26.40
(b)
Cost of each pen
= 26.40 ÷ 6
= $4.40
Answer(s): (a) $26.40; (b) $4.40
