6+5+2=13. There are 13 tennis balls in each bag. There are 3 bags. 13x3=39. Martina has 39 tennis balls in all.

39 tennis balls

Step-by-step explanation:

number of balls in each bag:

6 pink 5 yellow 2 white

thus, in total, one bag has: 6 + 5 + 2 = 13 balls.

And we are told that she has 3 of these bags, so we must multiply the 3 bags by the 13 balls each bag has:

total tennis balls = 3*13

total tennis balls = 39
