If chase won the next 18 matches then he will be able to get a 75% winning record.

Step-by-step explanation:

Let the no. of games chase has to win be 'y'.

He has won 18 matches out of 30.

If he won y matches more he will have a 75% winning record.

To find the percentage we should calculate,

  % = (no. Of matches won) x 100/ (total no. of matches)

As the no. of matches won increases, the total no. of matches also increases.

So y should be added to the matches won and also to the total no. of matches played.

[(18+y) /(30+y) ] x 100 = 75%

[(18+y) (100) ] = 75(30+y)

1800 + 100y = 2250 + 75y

100y - 75y = 2250 - 1800

25y = 450

y = 18

So if chase won next 18 matches then he will be able to get a 75%
