Question

At a tennis ball company, the average number of tennis balls placed in a case is 250. The number of tennis balls in a case can vary by as much a 3. Which inequality shows all of the possible numbers of tennis balls that can be in each case?

a.
253≤

Answer 1

Answer:247≤x≥253
Explanation:
let's say number of tennis balls is x
Since it varies by a maximum of 3, the lowest number of balls is 247 and the highest is 253
so x (number of tennis balls) is bigger than 247 and smaller than 253.

Answer 2

Answer:247≤x≥253

Explanation:

let's say number of tennis balls is x

Since it varies by a maximum of 3, the lowest number of balls is 247 and the highest is 253 so x (number of tennis balls) is bigger than 247 and smaller than 253.
