Cindy saved some of her school pocket money for 3 days. She saved $6 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?
- Cindy then spent all her savings on 6 identical notebooks. How much did each notebook cost?
(a)
Amount that Cindy saved on the first day = $6
Amount that Cindy saved on the second day = $6 + $0.80
Amount that Cindy saved on the third day = $6 + $0.80 + $0.80
Total amount the Cindy saved in 3 days
= 3 x 6 + 3 x 0.80
= 18 + 2.40
= $20.40
(b)
Cost of each notebook
= 20.40 ÷ 6
= $3.40
Answer(s): (a) $20.40; (b) $3.40
