35 of the muffins he made in the morning and half of the remainder in the afternoon. He had 18 muffins left unsold.
- How many muffins did he sell altogether?
- If he sold 4 muffins for $3.60, how much did he receive from the muffins he sold?
(a)
Fraction of the muffins left after selling in the morning
= 1 -
35 =
25 Fraction of the remaining muffins left after selling in the afternoon
= 1 -
12 =
12 Fraction of the muffins left after selling in the afternoon
=
12 x
25 =
210 Total number of muffins at first = 10 u
Number of muffins left = 2 u
2 u = 18
1 u = 18 ÷ 2 = 9
Number of muffins sold
= 10 u - 2 u
= 8 u
= 8 x 9
= 72
(b)
Number of sets of 4 muffins
= 72 ÷ 4
= 18
Amount that Rael received from the muffins he sold
= 18 x 3.60
= $64.80
Answer(s): (a) 72; (b) $64.80
