The number of each kind of kites sold are as follows;

number of small kite sold = 20

number of large kite sold = 10

How to find the number of each kind of kite sold?

The small kite cost = $4

The large kite cost = $7

Total money for the kite = $150

The number of kites sold = 30

Therefore,

let

x = number of small kite

y = number of large kite

Hence,

x + y = 30

4x + 7y = 150

4x + 4y  = 120

4x + 7y = 150

3y = 30

y = 30 / 3

y = 10

Therefore,

x = 30 - 10 = 20
