A garden supply store sells two types of lawn mowers. The cashiers kept a tally chart for the total number of mowers sold. They tallied 30 mowers sold. Total sales of mowers for the year were $8379.70. The small mowers cost $249.99 and the large mowers cost $329.99. Find the number of each type of mower sold.
The store did not sell any small mowers. They sold 25 large mowers.
The store sold 8 small mowers and 22 large mowers.
The store sold 11 small mowers and 19 large mowers.
The store sold 8 more small mowers than large mowers
Small = 30 - Large
249.99S + 329.99L = 8379.70
Substitute 30-L for S in second equation and solve for L. Insert that value into the first equation and solve for S. Check by inserting both values into the second equation.
