Answer:
Four-door sedan = 22
Two-door coupes = 6
Step-by-step explanation:
This is an algebra problem.
Let "<em>x</em>" represent number of four-door sedan,
"<em>y</em>" represent two-door coupe.
Since there are total of 28 autos on which film is applied, we have:
<em>x</em> + <em>y</em> = 28 Equation 1
<em>y </em>= 28 - <em>x </em>Equation 2
Also provided,
Total revenue = $3,459.72
That means,
129.99<em>x </em>+ 99.99<em>y</em> = 3,459.72 Equation 3
Putting value of "<em>y</em>" from Equation 2 in Equation 3 we have:
129.99<em>x</em> + 99.99(28 - <em>x</em>) = 3,459.72
129.99x + 2,799.72 - 99.99<em>x</em> = 3,459.72
30<em>x</em> = 660
<em>x </em>=
Therefore, number of four door sedans = 22
Further <em>y</em> that is two door sedan = 28 - <em>x = </em>28 - 22 = 6
