Victoria saved some of her school pocket money for 3 days. She saved $7 on the first day. For the remaining 2 days, she saved $0.20 more than the previous day.
- How much money did she save in 3 days?
- Victoria then spent all her savings on 6 identical pencils. How much did each pencil cost?
(a)
Amount that Victoria saved on the first day = $7
Amount that Victoria saved on the second day = $7 + $0.20
Amount that Victoria saved on the third day = $7 + $0.20 + $0.20
Total amount the Victoria saved in 3 days
= 3 x 7 + 3 x 0.20
= 21 + 0.60
= $21.60
(b)
Cost of each pencil
= 21.60 ÷ 6
= $3.60
Answer(s): (a) $21.60; (b) $3.60
