The correct option as per me is (b)
It would be a 90%. In the calculator 18 is what percent of 20.
<span>1/4(x + 16) - x =
First, distribute the 1/4.
= 1/4x + 1/4 * 16 - x
= 1/4x + 4 - x
= 1/4x + 4 - 4/4x
= 1/4x - 4/4x + 4
= -3/4x + 4

We can write an equation for this problem being, 500-(183+165)=152. So the answer is that your next must have a score of at least 152 or higher in order to win a bowling trophy.
