Eric sold
25 of the cupcakes he made in the afternoon and half of the remainder in the evening. He had 30 cupcakes left unsold.
- How many cupcakes did he sell altogether?
- If he sold 2 cupcakes for $1.70, how much did he receive from the cupcakes he sold?
(a)
Fraction of the cupcakes left after selling in the morning
= 1 -
25 =
35 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
35 =
310 Total number of cupcakes at first = 10 u
Number of cupcakes left = 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Number of cupcakes sold
= 10 u - 3 u
= 7 u
= 7 x 10
= 70
(b)
Number of sets of 2 cupcakes
= 70 ÷ 2
= 35
Amount that Eric received from the cupcakes he sold
= 35 x 1.70
= $59.50
Answer(s): (a) 70; (b) $59.50
