Ryan sold
35 of the wafers he made in the morning and half of the remainder in the afternoon. He had 8 wafers left unsold.
- How many wafers did he sell altogether?
- If he sold 4 wafers for $2.70, 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 = 8
1 u = 8 ÷ 2 = 4
Number of wafers sold
= 10 u - 2 u
= 8 u
= 8 x 4
= 32
(b)
Number of sets of 4 wafers
= 32 ÷ 4
= 8
Amount that Ryan received from the wafers he sold
= 8 x 2.70
= $21.60
Answer(s): (a) 32; (b) $21.60
