Question 811231
We are going to start by making 2 equations with the given information.
volleyball=x basketball=y
x+y=45 This the total amount we need
8x+11y=435 This is the amount we have to spend.
$8 per volleyball +$11 per basketball = $435 is what we have to spend



solve x+y=45 for x and plug x into the other equation.
x=-y+45
8(-y+45)+11y=435
-8y+360+11y=435
3y+360=435
3y=75
y=25


now plug y into x+y=45 to find x


x+25=45
x=20


We can get 20 volleyballs and 25 basketballs.
