Maya wants to buy some markers of the same price. If she buys 3 markers, she will have $6.30 left. If she buys 5 markers, she will short of $2.70.
- How much does each marker cost?
- How much does Maya have?
(a)
Difference in the number of markers
= 5 - 3
= 2
Amount that Maya needs to buy 2 markers
= 6.30 + 2.70
= $9.00
Cost of each marker
= 9.00 ÷ 2
= $4.50
(b)
Amount that Maya has
= 3 x 4.50 + 6.30
= $19.80
Answer(s): (a) $4.50; (b) $19.80
