Elijah sold
35 of the wafers he made in the morning and half of the remainder in the afternoon. He had 14 wafers left unsold.
- How many wafers did he sell altogether?
- If he sold 2 wafers for $4.20, 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 = 14
1 u = 14 ÷ 2 = 7
Number of wafers sold
= 10 u - 2 u
= 8 u
= 8 x 7
= 56
(b)
Number of sets of 2 wafers
= 56 ÷ 2
= 28
Amount that Elijah received from the wafers he sold
= 28 x 4.20
= $117.60
Answer(s): (a) 56; (b) $117.60
