Luke sold
25 of the scones he made in the afternoon and half of the remainder in the evening. He had 12 scones left unsold.
- How many scones did he sell altogether?
- If he sold 2 scones for $1.80, how much did he receive from the scones he sold?
(a)
Fraction of the scones left after selling in the morning
= 1 -
25 =
35 Fraction of the remaining scones left after selling in the afternoon
= 1 -
12 =
12 Fraction of the scones left after selling in the afternoon
=
12 x
35 =
310 Total number of scones at first = 10 u
Number of scones left = 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of scones sold
= 10 u - 3 u
= 7 u
= 7 x 4
= 28
(b)
Number of sets of 2 scones
= 28 ÷ 2
= 14
Amount that Luke received from the scones he sold
= 14 x 1.80
= $25.20
Answer(s): (a) 28; (b) $25.20
