An equation is formed when two equal expressions. Ms. Kilicoglu will buy 20 volleyballs and 25 basketballs.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let x be the number of volleyballs and y be the number of basketballs. Therefore, the total number of balls can be written as,
x + y = 45
x = 45 - y
Each volleyball costs $8 and each basketball costs $11. Also, Ms. Kilicoglu has only $435, therefore,
8x + 11y = 435
8(45 - y) + 11y = 435
360 - 8y + 11y = 435
3y = 75
y = 25
Substitute the value of y in the first equation,
x + y = 45
x + 25 = 45
x = 20
Hence, Ms. Kilicoglu will buy 20 volleyballs and 25 basketballs.
