Set the two equation equal to each other to solve for x. Angles are acute because they are less than 90 degrees.
We are given the statement:
She gets a base pay of $80 a day plus 5 percent of the
value of any merchandise she sells that exceeds a total of $400
Then we are given the equation:
Earnings = 400 + 0.05 (t – 80)
Now if we read the statement carefully, we can understand
that the base pay is $80 and NOT $400. Therefore it should be the constant
value in the equation. Now the statement also tells that what will be added to
her pay is anything beyond 400, therefore it should be the one inside the
parenthesis. That is:
<span>Earnings = 80 + 0.05 (t – 400) ---> correct equation</span>
Now we use the corrected equation to solve for the earnings
when t = 475
Earnings = 80 + 0.05 (475 – 400)
<span>Earnings = 83.75 dollars</span>
