Jack sold
25 of the scones he made in the afternoon and half of the remainder in the evening. He had 18 scones left unsold.
- How many scones did he sell altogether?
- If he sold 3 scones for $2.70, 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 = 18
1 u = 18 ÷ 3 = 6
Number of scones sold
= 10 u - 3 u
= 7 u
= 7 x 6
= 42
(b)
Number of sets of 3 scones
= 42 ÷ 3
= 14
Amount that Jack received from the scones he sold
= 14 x 2.70
= $37.80
Answer(s): (a) 42; (b) $37.80
