Question 3518
<center>{{{C = 3+.20x}}}</center>

4.70 = 3+.20x
<br>
Subtract 3 from each side to isolate the variable.
4.70-3 = 3+.20x-3
1.70 = .20x
<br>
Divide .20 from each side:
1.70/.20 = .20x/.20
8.5 = x
<br>
Check:
4.70 = 3+(.20)(8.5)
4.70 = 3+1.7
4.70 = 4.70 <p> <marquee behavior="alternate">Solved By: NtNk</marquee>
