Nicole saved some of her school pocket money for 3 days. She saved $6 on the first day. For the remaining 2 days, she saved $0.30 more than the previous day.
- How much money did she save in 3 days?
- Nicole then spent all her savings on 3 identical notebooks. How much did each notebook cost?
(a)
Amount that Nicole saved on the first day = $6
Amount that Nicole saved on the second day = $6 + $0.30
Amount that Nicole saved on the third day = $6 + $0.30 + $0.30
Total amount the Nicole saved in 3 days
= 3 x 6 + 3 x 0.30
= 18 + 0.90
= $18.90
(b)
Cost of each notebook
= 18.90 ÷ 3
= $6.30
Answer(s): (a) $18.90; (b) $6.30
