Answer:
Step-by-step explanation:
C=25x+75 would be the equation
Step-by-step explanation:
75 dollars is the flat out fee right away and the 25 is for how many hours spent fixing the drain
15x-10=20
+10 +10
15x=30
\15 /15
x=2
you add 10 to both -10 (they cancek eachother out) and 20 (equals 30)
Then you divide 30 by 15 (equals 2) and 15 by 15 (they cancel eachother out)
Then you get x=2
