Raeann saved some of her school pocket money for 3 days. She saved $9 on the first day. For the remaining 2 days, she saved $0.60 more than the previous day.
- How much money did she save in 3 days?
- Raeann then spent all her savings on 9 identical markers. How much did each marker cost?
(a)
Amount that Raeann saved on the first day = $9
Amount that Raeann saved on the second day = $9 + $0.60
Amount that Raeann saved on the third day = $9 + $0.60 + $0.60
Total amount the Raeann saved in 3 days
= 3 x 9 + 3 x 0.60
= 27 + 1.80
= $28.80
(b)
Cost of each marker
= 28.80 ÷ 9
= $3.20
Answer(s): (a) $28.80; (b) $3.20
