Question

Alexa wants to have a bowling average of at least 210. If her scores are 230, 185, and 195, what does she need to score on her fourth game? Which inequality best represents the situation?

Answer 1

Step-by-step explanation:

so her minimum 4th score is calculated this way:

$\frac{230 + 185 + 195 + x}{4} = 210 \\ 610 + x = 840 \\ x = 230$

so in round four

her score should be x in the way that:

x≥230
