Answer: x=2.5
Step-by-step explanation:
First we need to set up and equation
10= 60 - 20x
where x is the amount the cookies cost
subtract 60 from both sides
-50=- 20x
now divide each side by 20 so hat we can isolate the x

x= 2.5
now to check just multiply it by 20 then subtract from 60.
2.5 x 10= 50
60-50=10
