Zara saved some of her school pocket money for 3 days. She saved $3 on the first day. For the remaining 2 days, she saved $0.60 more than the previous day.
- How much money did she save in 3 days?
- Zara then spent all her savings on 6 identical pens. How much did each pen cost?
(a)
Amount that Zara saved on the first day = $3
Amount that Zara saved on the second day = $3 + $0.60
Amount that Zara saved on the third day = $3 + $0.60 + $0.60
Total amount the Zara saved in 3 days
= 3 x 3 + 3 x 0.60
= 9 + 1.80
= $10.80
(b)
Cost of each pen
= 10.80 ÷ 6
= $1.80
Answer(s): (a) $10.80; (b) $1.80
