35 of the macarons he made in the afternoon and half of the remainder in the evening. He had 18 macarons left unsold.
- How many macarons did he sell altogether?
- If he sold 3 macarons for $3.60, how much did he receive from the macarons he sold?
(a)

35 =
25 Fraction of the remaining macarons left after selling in the afternoon

12 Fraction of the macarons left after selling in the afternoon
=
12 x
25 =
210 Total number of macarons at first = 10 u
Number of macarons left = 2 u
2 u = 18
1 u = 18 ÷ 2 = 9
Number of macarons sold
= 10 u - 2 u
= 8 u
= 8 x 9
= 72
(b)

= 72 ÷ 3
= 24
Amount that Ahmad received from the macarons he sold
= 24 x 3.60
= $86.40
