Riordan sold
25 of the croissants he made in the morning and half of the remainder in the evening. He had 30 croissants left unsold.
- How many croissants did he sell altogether?
- If he sold 5 croissants for $4.60, 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 = 30
1 u = 30 ÷ 3 = 10
Number of croissants sold
= 10 u - 3 u
= 7 u
= 7 x 10
= 70
(b)
Number of sets of 5 croissants
= 70 ÷ 5
= 14
Amount that Riordan received from the croissants he sold
= 14 x 4.60
= $64.40
Answer(s): (a) 70; (b) $64.40
