Studdy Solution

STEP 1

Assumptions1. John uses5 tennis balls in every practice game. . Maya uses3 tennis balls in every practice game.
3. They played3 practice games.

STEP 2

First, we need to find out how many tennis balls John uses in practice games. We can do this by multiplying the number of tennis balls John uses in one game by the number of games.
$John's\, tennis\, balls = Number\, of\, balls\, per\, game \\times Number\, of\, games$

STEP 3

Now, plug in the given values for the number of balls per game and the number of games to calculate the total number of balls John used.
$John's\, tennis\, balls =5 \\times3$

STEP 4

Calculate the total number of balls John used.
$John's\, tennis\, balls = \\times3 =15$

STEP 5

Next, we need to find out how many tennis balls Maya uses in3 practice games. We can do this by multiplying the number of tennis balls Maya uses in one game by the number of games.
$Maya's\, tennis\, balls = Number\, of\, balls\, per\, game \\times Number\, of\, games$

STEP 6

Now, plug in the given values for the number of balls per game and the number of games to calculate the total number of balls Maya used.
$Maya's\, tennis\, balls =3 \\times3$

STEP 7

Calculate the total number of balls Maya used.
$Maya's\, tennis\, balls =3 \\times3 =9$

STEP 8

Now that we have the total number of balls used by John and Maya, we can add these to find the total number of balls they used together.
$Total\, tennis\, balls = John's\, tennis\, balls + Maya's\, tennis\, balls$

STEP 9

Plug in the values for John's tennis balls and Maya's tennis balls to calculate the total number of balls.
$Total\, tennis\, balls =15 +9$

STEP 10

Calculate the total number of balls they used together.
$Total\, tennis\, balls =15 +9 =24$ John and Maya used24 tennis balls in3 practice games.
