Tom sold
35 of the tarts he made in the morning and half of the remainder in the evening. He had 4 tarts left unsold.
- How many tarts did he sell altogether?
- If he sold 2 tarts for $2.10, how much did he receive from the tarts he sold?
(a)
Fraction of the tarts left after selling in the morning
= 1 -
35 =
25 Fraction of the remaining tarts left after selling in the afternoon
= 1 -
12 =
12 Fraction of the tarts left after selling in the afternoon
=
12 x
25 =
210 Total number of tarts at first = 10 u
Number of tarts left = 2 u
2 u = 4
1 u = 4 ÷ 2 = 2
Number of tarts sold
= 10 u - 2 u
= 8 u
= 8 x 2
= 16
(b)
Number of sets of 2 tarts
= 16 ÷ 2
= 8
Amount that Tom received from the tarts he sold
= 8 x 2.10
= $16.80
Answer(s): (a) 16; (b) $16.80
