Question 406619: This is an application problem that involves Inequalities.
Betty bowled 3 games. After the first 2 games, her scores were 200 and 90. Her average score was 140. What did she bowl in the 3rd game? There is a hint: use the variable x for what she bowled in the 3rd game and write an equation.

The average is 140, so

(200 + 90 + x)/3 = 140

200 + 90 + x = 420 --> 290 + x = 420 --> x = 130.
