Question

To get on the top players’ list, Don needs to have a minimum average score of 225 after playing four games. His scores on his first three games were 192, 214, and 250. What is the minimum score Don needs to earn on his fourth game? Enter your answer in the box.

Answer 1

Remark

The scores of the 4 games are  192 + 214 + 250 + x

When you divide these scores by 4 you need to get 225.

Equation

$\dfrac{192 + 214+ 250+x}{4} = 225$

Solution

Add the 3 numbers together

(656 + x)/4 = 225     Multiply both sides by 4

656 + x = 225*4

656 + x = 900          Subtract 656 from both sides.

x = 900 - 656

x = 244                     His 4th game has to be 244 or higher.

Answer 2

244 is the correct answer
