Answer:
85
Step-by-step explanation:
Important Info:
Frank has 9 packs of red bouncy balls and 4 packs of yellow bouncy balls
Each pack contains 17 balls
So to find number of red balls and yellow balls we simply multiply the number of packs he has by the number of balls that are in each pack
For red:
He has 9 packs
There are 17 balls in each pack
He has a total of 9 * 17 = 153 red bouncy balls
For yellow
He has 4 packs
Each back contains 17 balls
He has a total of 4 * 17 = 68 yellow bouncy balls.
We want to find how many more red balls he has than yellow balls.
To find this we simply find the difference between the number of red balls he has and the number of yellow balls he has.
153 - 68 = 85
He has 85 more red balls than yellow balls.
