Answer:
Hardy has 470 more tennis balls than Kerns.
Explanation:
Given that:
Total number of tennis balls = 940
Let,
x represents the number of tennis balls Hardy has.
y represents the number of tennis balls Kerns has.
According to given statement,
x+y=940 Eqn 1
x = 3y Eqn 2
Putting x = 3y in Eqn 1
3y+y=940
4y=940
Dividing both sides by 4
![(4y)/(4)=(940)/(4)\\y=235](https://img.qammunity.org/2021/formulas/mathematics/college/ner2a5gcllzfeq1vvlsfzkbfu2ul48jaq6.png)
Putting y=235 in Eqn 2
x = 3(235)
x = 705
Difference = Hardy's tennis balls - Kerns' tennis balls
Difference = 705 - 235 = 470
Hence,
Hardy has 470 more tennis balls than Kerns.
