Answer:
32.2 is your answer for c
Step-by-step explanation:
Note the equation:
c - 23.7 = 8.5
Note the equal sign. What you do to one side, you do to the other. Isolate the c. add 23.7 to both sides
c - 23.7 (+23.7) = 8.5 (+23.7)
c = 8.5 + 23.7
Simplify.
c = 32.2
32.2 is your answer for c

Answer:
v = 875
Step-by-step explanation:
0.01v + 0.09(8000-v) = 650
Multiply the parenthesis
0.01v + 720 - .09v = 650
Combine like terms
720 - 0.08v = 650
Add 0.08v to both sides
720 = 650 + 0.08v
Subtract 650 from both sides
70 = 0.08v
Divide by 0.08 on both sides
v = 875
Hope this helps :)
