Asher received $2 from his mother in the 1st week of school and $7 in the 2nd week. Each week, he receives $5 more than the week before.
- How much money did he received in the 7th week?
- In which week did he receive $27?
(a)
Amount that Asher received on 1st Week = $2
Amount that Asher received on 2nd Week = $6
Formula:
Amount received each week = 2 + (Week number - 1) x $5
Amount received on Week 7
= 2 + (7 - 1) x 5
= 2 + 6 x 5
= 2 + 30
= $32
(b)
Week number that Asher received $27
= [(27 - 2) ÷ 5] + 1
= (25 ÷ 5) + 1
= 5 + 1
= 6
Answer(s): (a) $32; (b) 6
