Henry sold
35 of the puffs he made in the morning and half of the remainder in the evening. He had 16 puffs left unsold.
- How many puffs did he sell altogether?
- If he sold 4 puffs for $2.40, how much did he receive from the puffs he sold?
(a)
Fraction of the puffs left after selling in the morning
= 1 -
35 =
25 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
25 =
210 Total number of puffs at first = 10 u
Number of puffs left = 2 u
2 u = 16
1 u = 16 ÷ 2 = 8
Number of puffs sold
= 10 u - 2 u
= 8 u
= 8 x 8
= 64
(b)
Number of sets of 4 puffs
= 64 ÷ 4
= 16
Amount that Henry received from the puffs he sold
= 16 x 2.40
= $38.40
Answer(s): (a) 64; (b) $38.40
