small nower x numbers
large mower y numbers
...
x+y=30 .............1
249.99x+ 329.99y =8379.7 .............2

multiply (1)by -329.99
Multiply (2) by 1
-329.99 x-329.99 y=-9899.7
249.99x +329.99y =8379.7

Add the two equations
-80x=-1520
/-80
x=19 small mowers
plug value of x in (1)
x+y=30
19+y=30
y=30-19
y=11 larger mowers
