Howard sold
25 of the croissants he made in the afternoon and half of the remainder in the evening. He had 12 croissants left unsold.
- How many croissants did he sell altogether?
- If he sold 4 croissants for $4.30, 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 = 12
1 u = 12 ÷ 3 = 4
Number of croissants sold
= 10 u - 3 u
= 7 u
= 7 x 4
= 28
(b)
Number of sets of 4 croissants
= 28 ÷ 4
= 7
Amount that Howard received from the croissants he sold
= 7 x 4.30
= $30.10
Answer(s): (a) 28; (b) $30.10
