Simon sold
25 of the shortbreads he made in the morning and half of the remainder in the evening. He had 30 shortbreads left unsold.
- How many shortbreads did he sell altogether?
- If he sold 5 shortbreads for $3.70, 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 = 30
1 u = 30 ÷ 3 = 10
Number of shortbreads sold
= 10 u - 3 u
= 7 u
= 7 x 10
= 70
(b)
Number of sets of 5 shortbreads
= 70 ÷ 5
= 14
Amount that Simon received from the shortbreads he sold
= 14 x 3.70
= $51.80
Answer(s): (a) 70; (b) $51.80
