Question

Allie is in a bowling tournament that consists of 5 games. She has already bowled 4. Her scores for the 4 games were 220, 245, 270, and 280. What does Allie need to bowl for her 5th game to get an average score of 260?

Answer 1

Hey!

To get an average of 260 for 5 games, the total must be:

$260 \times 5 = 1,300$

The total must be 1,300. Add the 4 scores and see what it adds up to. Then subtract that from 1,300

$220 + 245 + 270 + 280 = 1,015$

Subtract that from 1,300 to get your answer

$1,300 - 1,015 = 285$

That means her score has to be 285
