Ethan sold
25 of the muffins he made in the morning and half of the remainder in the afternoon. He had 9 muffins left unsold.
- How many muffins did he sell altogether?
- If he sold 3 muffins for $3.30, how much did he receive from the muffins he sold?
(a)
Fraction of the muffins left after selling in the morning
= 1 -
25 =
35 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
35 =
310 Total number of muffins at first = 10 u
Number of muffins left = 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Number of muffins sold
= 10 u - 3 u
= 7 u
= 7 x 3
= 21
(b)
Number of sets of 3 muffins
= 21 ÷ 3
= 7
Amount that Ethan received from the muffins he sold
= 7 x 3.30
= $23.10
Answer(s): (a) 21; (b) $23.10
