Susan and betsy bought sport supplies for summer camp. susan bought six basketballs and one soccer ball for $27. betsy bought four basketballs and two soccer balls for $22. how much do basketballs cost? how much do soccer balls cost?

For this case, the first thing we must do is define variables:

x: cost of each basketball

y: cost of each soccer ball

We now write the system of equations:

6x + y = 27

4x + 2y = 22

Solving the system we have:

x = 4 $

y = 3 $

Answer:

basketballs cost $ 4

soccer balls cost $ 3
