Ivory saved some of her school pocket money for 3 days. She saved $11 on the first day. For the remaining 2 days, she saved $0.40 more than the previous day.
- How much money did she save in 3 days?
- Ivory then spent all her savings on 6 identical notebooks. How much did each notebook cost?
(a)
Amount that Ivory saved on the first day = $11
Amount that Ivory saved on the second day = $11 + $0.40
Amount that Ivory saved on the third day = $11 + $0.40 + $0.40
Total amount the Ivory saved in 3 days
= 3 x 11 + 3 x 0.40
= 33 + 1.20
= $34.20
(b)
Cost of each notebook
= 34.20 ÷ 6
= $5.70
Answer(s): (a) $34.20; (b) $5.70
