Japheth sold
25 of the croissants he made in the afternoon and half of the remainder in the evening. He had 18 croissants left unsold.
- How many croissants did he sell altogether?
- If he sold 2 croissants for $3.20, how much did he receive from the croissants he sold?
(a)
Fraction of the croissants left after selling in the morning
= 1 -
25 =
35 Fraction of the remaining croissants left after selling in the afternoon
= 1 -
12 =
12 Fraction of the croissants left after selling in the afternoon
=
12 x
35 =
310 Total number of croissants at first = 10 u
Number of croissants left = 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Number of croissants sold
= 10 u - 3 u
= 7 u
= 7 x 6
= 42
(b)
Number of sets of 2 croissants
= 42 ÷ 2
= 21
Amount that Japheth received from the croissants he sold
= 21 x 3.20
= $67.20
Answer(s): (a) 42; (b) $67.20
