Question 80518
Given:
.
{{{y=0.55x+7}}}
.
in which y equals the hourly wage in dollars and x is the number of units produced
per hour.
.
You are asked to find the hourly wage of a worker who produces 13 units per hour.
.
All you have to do is to refer to the equation and substitute 13 for x.  If you do that, you
get:
.
{{{y = 0.55*13 + 7}}}
.
Do the multiplication on the right side and the equation becomes:
.
{{{y = 7.15 + 7}}}
.
Now add the two terms on the right side of the equation to get:
.
{{{y = 14.15}}}
.
That's the answer.  A worker who produces 13 units per hour earns a wage of $14.15 per hour.
.
Hope this helps you to understand the problem a little better.
