Tim sold
35 of the cupcakes he made in the morning and half of the remainder in the afternoon. He had 4 cupcakes left unsold.
- How many cupcakes did he sell altogether?
- If he sold 2 cupcakes for $2.40, how much did he receive from the cupcakes he sold?
(a)
Fraction of the cupcakes left after selling in the morning
= 1 -
35 =
25 Fraction of the remaining cupcakes left after selling in the afternoon
= 1 -
12 =
12 Fraction of the cupcakes left after selling in the afternoon
=
12 x
25 =
210 Total number of cupcakes at first = 10 u
Number of cupcakes left = 2 u
2 u = 4
1 u = 4 ÷ 2 = 2
Number of cupcakes sold
= 10 u - 2 u
= 8 u
= 8 x 2
= 16
(b)
Number of sets of 2 cupcakes
= 16 ÷ 2
= 8
Amount that Tim received from the cupcakes he sold
= 8 x 2.40
= $19.20
Answer(s): (a) 16; (b) $19.20
