Fiona saved some of her school pocket money for 3 days. She saved $8 on the first day. For the remaining 2 days, she saved $0.10 more than the previous day.
- How much money did she save in 3 days?
- Fiona then spent all her savings on 9 identical pens. How much did each pen cost?
(a)
Amount that Fiona saved on the first day = $8
Amount that Fiona saved on the second day = $8 + $0.10
Amount that Fiona saved on the third day = $8 + $0.10 + $0.10
Total amount the Fiona saved in 3 days
= 3 x 8 + 3 x 0.10
= 24 + 0.30
= $24.30
(b)
Cost of each pen
= 24.30 ÷ 9
= $2.70
Answer(s): (a) $24.30; (b) $2.70
