Answer:
$975
Step-by-step explanation:
If you add the first row and last row you can get a multiple of 100
so you get an area off 2000 for 1200 divide both by 20 to get 100 area for 60
Now that you have one hundred you can subtract the last row by 100 to get to 1500 so it costs 900 for 1500 square feet
To find save on lawns price multiply by 35 percent so 1500 x 35% = 525 and finally 1500 - 525 from the 35% cheaper to get the price of 975 square feet
