Answer:

The number of small mowers are 19 and the large mowers are 11.

Step-by-step explanation:

Given:

A garden supply store sells two types of lawn mowers. Total sales of mowers for the year were $8379.70. The total number of mowers sold the 30. The small mower cost $249.99 and the large mower costs $329.99.

Now, to find the number of each type of mower sold.

Let the number of small mower be [tex]x.[/tex]

And the number of large mower be  [tex]y.[/tex]

So, total number of mowers are:

[tex]x+y=30[/tex]

[tex]x=30-y\ \ \ ....(1)[/tex]

Now, the total sales of mowers are:

[tex]249.99(x)+329.99(y)=8379.70[/tex]

Substituting the value of [tex]x[/tex] from equation (1) we get:

[tex]249.99(30-y)+329.99y=8379.70[/tex]

[tex]7499.7-249.99y+329.99y=8379.70[/tex]

[tex]7499.7+80y=8379.70[/tex]

Subtracting both sides by 7499.7 we get:

[tex]80y=880[/tex]

Dividing both sides by 80 we get:

[tex]y=11.[/tex]

The number of large mower = 11.

Now, to get the number of small mowers we substitute the value of [tex]y[/tex]  in equation ( 1 ):

[tex]x=30-y\\x=30-11\\x=19.[/tex]

The number of small mower = 19.

Therefore, the number of small mowers are 19 and the large mowers are 11.
