Question

7. A shopkeeper can buy 36 toys for $20.52. What will he pay for 120 toys

Step by step explansion ​

Answer 1

$68.4

Explanation:

Let x represent the required cost.

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

x : 20.52 = 120 : 36

i.e. x/20.52 = 120/36

x =
`(120 * 20.52)/(36)`

x = 10 * 6.84

x = 68.4

∴ The cost is $68.4.

Hope this helps!!
