A garden supply store sells two types of lawn mowers. The smaller mower costs $249.99 and the larger mower cost $329.99. If 30 total mowers were sold and the total sales for a given year was $8379.70, find how many of each type were sold.

19 smaller lawn mowers & 11 larger lawn mowers.

Step-by-step explanation:

249.99x + 329.99*30-329.99x = 8379.70

-80x + 9899.70 = 8379.70

-80x = -1520.00

x = 19 (smaller lawn mowers)

30-x = 11 (larger lawn mowers)

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
