You use 66 gallons of water on 2020 plants in your garden. At that rate, how much water will it take to water 3030 plants?

99 gallons bc for each 1,010 plants their is 33 gallons so multiplying by 3 you will get 99 gallons for 3,030 plants 

proportion 66/2020 = x/3030 now you will cross multiply the number 3030 by 66 then divide by 2020 so x=99
