Warren sold
25 of the puffs he made in the afternoon and half of the remainder in the evening. He had 24 puffs left unsold.
- How many puffs did he sell altogether?
- If he sold 2 puffs for $3.10, how much did he receive from the puffs he sold?
(a)
Fraction of the puffs left after selling in the morning
= 1 -
25 =
35 Fraction of the remaining puffs left after selling in the afternoon
= 1 -
12 =
12 Fraction of the puffs left after selling in the afternoon
=
12 x
35 =
310 Total number of puffs at first = 10 u
Number of puffs left = 3 u
3 u = 24
1 u = 24 ÷ 3 = 8
Number of puffs sold
= 10 u - 3 u
= 7 u
= 7 x 8
= 56
(b)
Number of sets of 2 puffs
= 56 ÷ 2
= 28
Amount that Warren received from the puffs he sold
= 28 x 3.10
= $86.80
Answer(s): (a) 56; (b) $86.80
