Bryan sold
35 of the wafers he made in the afternoon and half of the remainder in the evening. He had 10 wafers left unsold.
- How many wafers did he sell altogether?
- If he sold 5 wafers for $3.90, how much did he receive from the wafers he sold?
(a)
Fraction of the wafers left after selling in the morning
= 1 -
35 =
25 Fraction of the remaining wafers left after selling in the afternoon
= 1 -
12 =
12 Fraction of the wafers left after selling in the afternoon
=
12 x
25 =
210 Total number of wafers at first = 10 u
Number of wafers left = 2 u
2 u = 10
1 u = 10 ÷ 2 = 5
Number of wafers sold
= 10 u - 2 u
= 8 u
= 8 x 5
= 40
(b)
Number of sets of 5 wafers
= 40 ÷ 5
= 8
Amount that Bryan received from the wafers he sold
= 8 x 3.90
= $31.20
Answer(s): (a) 40; (b) $31.20
