Question : 18

Total: 50

Solution:

Concept:

Profit is made when the total selling price is greater than the total cost price of the oranges sold.

Explanation:

The boy bought 5 oranges for

\#24.00

Cost price per orange

= \frac{24}{5} = \#4.80

He sold 4 oranges for

\#30.00

Selling price per orange

= \frac{30}{4} = \#7.50

Profit per orange

= \#7.50 - \#4.80 = \#2.70

For the 4 oranges sold, total profit

= 4 \times \#2.70 = \#10.80

Answer:

\#10.80
