Charlie sold
25 of the shortbreads he made in the afternoon and half of the remainder in the evening. He had 6 shortbreads left unsold.
- How many shortbreads did he sell altogether?
- If he sold 2 shortbreads for $3.60, how much did he receive from the shortbreads he sold?
(a)
Fraction of the shortbreads left after selling in the morning
= 1 -
25 =
35 Fraction of the remaining shortbreads left after selling in the afternoon
= 1 -
12 =
12 Fraction of the shortbreads left after selling in the afternoon
=
12 x
35 =
310 Total number of shortbreads at first = 10 u
Number of shortbreads left = 3 u
3 u = 6
1 u = 6 ÷ 3 = 2
Number of shortbreads sold
= 10 u - 3 u
= 7 u
= 7 x 2
= 14
(b)
Number of sets of 2 shortbreads
= 14 ÷ 2
= 7
Amount that Charlie received from the shortbreads he sold
= 7 x 3.60
= $25.20
Answer(s): (a) 14; (b) $25.20
