Nick chapp manages an auto film outlet that applies window film to automobile windows. he reported that this past week, a total of 23 autos had window film applied. auto film charges $189.99 for a four-door sedan and $159.99 for a two-door coupe. if nick had total receipts for the week of $4189.77, how many four-door sedans had been serviced? how many two-door coupes?

Let, the number of four door sedans = x

And the number of two door coupes = y

Given a total of 23 autos had window film applied.

So we can write the equation as, .....equation 1

The charge of auto film for a four door sedan = $189.99.

Now the charge of auto film for x four door sedans = $ = $

Also given, the charge of auto film for a two door coupe = $159.99.

So, the charge of auto film for y two doos coupes = $ = $

The total receipts for the week = $4189.77

So we can write the equation as,

.....equation 2

From equation 1, we can write,

Now by substituting this value of x in equation 2 we will get,

By distributing 189.99 we will get,

To get y first we move 30y to the right side by adding it to both sides. We will get,

Now to get y , we will move 4189.77 to the left side by subtracting it from both sides. We will get,

Now to get , we will move 30 to the left side by dividing it to both sides. We will get,

So we have got the number of two door coupes = 6

The number of four door sedans = .

We have got the required answer here.

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
