Oscar sold
35 of the shortbreads he made in the morning and half of the remainder in the evening. He had 8 shortbreads left unsold.
- How many shortbreads did he sell altogether?
- If he sold 2 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 -
35 =
25 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
25 =
210 Total number of shortbreads at first = 10 u
Number of shortbreads left = 2 u
2 u = 8
1 u = 8 ÷ 2 = 4
Number of shortbreads sold
= 10 u - 2 u
= 8 u
= 8 x 4
= 32
(b)
Number of sets of 2 shortbreads
= 32 ÷ 2
= 16
Amount that Oscar received from the shortbreads he sold
= 16 x 3.70
= $59.20
Answer(s): (a) 32; (b) $59.20
