Hilda saved some of her school pocket money for 3 days. She saved $5 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?
- Hilda then spent all her savings on 6 identical markers. How much did each marker cost?
(a)
Amount that Hilda saved on the first day = $5
Amount that Hilda saved on the second day = $5 + $0.20
Amount that Hilda saved on the third day = $5 + $0.20 + $0.20
Total amount the Hilda saved in 3 days
= 3 x 5 + 3 x 0.20
= 15 + 0.60
= $15.60
(b)
Cost of each marker
= 15.60 ÷ 6
= $2.60
Answer(s): (a) $15.60; (b) $2.60
