Each can of tennis balls has x balls. Initially, Sam has 14 cans of tennis balls, plus 3 extra balls. Jerri initially has 7 cans of tennis balls, plus 8 extra balls. If Jerri doubles the number of tennis balls she has, how many more balls will she have than Sam has?

number of tennis balls Sam has = 14x + 3

number of tennis balls Jerri has = 7x + 8

double the number of tennis balls Jerri has = 2 * (7x + 8)

double the number of tennis balls Jerri has = 14x + 16

14x + 16 is how many more than 14x + 3 ?

(14x + 16) - (14x + 3) = 14x + 16 - 14x - 3 = 16 - 3 = 13

If Jerri doubles the number of tennis balls she has, she will have 13 more balls than Sam has.
