Lee sold
25 of the puffs he made in the morning and half of the remainder in the afternoon. He had 15 puffs left unsold.
- How many puffs did he sell altogether?
- If he sold 5 puffs for $2.10, 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 = 15
1 u = 15 ÷ 3 = 5
Number of puffs sold
= 10 u - 3 u
= 7 u
= 7 x 5
= 35
(b)
Number of sets of 5 puffs
= 35 ÷ 5
= 7
Amount that Lee received from the puffs he sold
= 7 x 2.10
= $14.70
Answer(s): (a) 35; (b) $14.70
