Subtract x on both sides the result you divide it by 5
10 is the initial value, found when x=0. I don't know what you are measuring by "0" and "10" here, so can't be more specific.
15A- Damon earns around $320 (32 x 10)
15B - Damon earns $344.00 a week (32 x 10.75)
15C - Yes
The real answer is y=-1/2+9 !
15% = 3/20
Therefore, 15% of 60 is:
3/20 * 60
= 180/20
= 9
