Question

7. A shopkeeper can buy 36 toys for $20.52. What will be
for 120 toys?​

Answer 1

$68.40

Explanation:

Let x represent the required cost.

Since the number of toys is directly proportional to the cost:

x : $20.52 = 120 : 36

i.e. x/$20.52 = 120/36

x = (
`\frac{120 * $20.52}`)/36

x = $2462.40/36

x = $68.40

Hope this helps!!!
