Wendy saved some of her school pocket money for 4 days. She saved $3 on the first day. For the remaining 3 days, she saved $0.20 more than the previous day.
- How much money did she save in 4 days?
- Wendy then spent all her savings on 2 identical pens. How much did each pen cost?
(a)
Amount that Wendy saved on the first day = $3
Amount that Wendy saved on the second day = $3 + $0.20
Amount that Wendy saved on the third day = $3 + $0.20 + $0.20
Amount that Wendy saved on the fourth day = $3 + $0.20 + $0.20 + $0.20
Total amount the Wendy saved in 4 days
= 4 x 3 + 6 x 0.20
= 12 + 1.20
= $13.20
(b)
Cost of each pen
= 13.20 ÷ 2
= $6.60
Answer(s): (a) $13.20; (b) $6.60
