Answer:

A  $12.84

Step-by-step explanation:

Sweater was originally $48.00 before tax.  $48.00 x 7% tax rate (.07) = $3.36 in tax

So the sweater originally would've cost $48.00 + $3.36 = $51.36

The sale price was 25% off the $48.00.  $48.00 x 25% (.25) = $12.00

Then you subtract the $12.00 from the $48.00 to get the new price of $36.00

Now that's before tax, so $36.00 x 7% tax rate (.07) = $2.52 in tax

So the sweater would cost on sale $36.00 + $2.52 = $38.52

To figure out how much she would've saved you subtract the sale price & tax from the original price & tax $51.36 - $38.52 = $12.84

Aisha wants to paint the four walls of her living room.
sergiy2304 [10]

The total amount Aisha would pay to paint her room is $54.

<h3>What is the cost of painting the rooms?</h3>

The first step is to determine the area of the walls. The walls have the shape of a rectangle. Thus, the formula for the area of a rectangle would be used to determine the area of the wall.

Area of the three walls without a door : 3 x (length x width)

3 x (2.4 x 5.2) = 37.44 m²

Area of the fourth wall with a door : area of the wall - area of the door

(2.4 x 5.2) - (2 x 0.8) = 10.88m²

Total area of the walls : area of the three walls + area of the wall with the door

10.88m² + 37.44 m² = 48.32 m²

The next step is to determine the number of tins that would be needed:

48.32 /12 = 4.03

5 tins would needed

Cost of the 5 tins: (4 x 12) + (0.5 x 12) = $54

Find the slope of the line that passes through the points (2,1) and (-7,4)
VladimirAG [237]

Answer:

-\frac13

Step-by-step explanation:

Just the slope, so we can simply apply the definition, as variation in y over the variation in x

m= \frac{\Delta y}{\Delta x} = \frac{1-4}{2-(-7)} = \frac {-3}{9} = -\frac13

The local business will donate $5.00 for every 10 tickets sold. Let x represent tickets sold, and y represent dollars donated. S
nydimaria [60]

Answer:

If we let x be the number of ticket sold and y be the amount in dollars donated then, the equation would be,

                                     x = 2y

We can check our answer by substituting the given,

                                     10 = 2(5)

                                      10 = 10

The equation can also be written as,

                                    y = (1/2)x

Student B is correct.

Austin pays $2 per day for high speed internet. The equation y = 2x relates his internet charges (y) to the number of days (x) h
Alika [10]

Answer:

Option C. 2

Step-by-step explanation:

Let

x ----> the number of days

y ----> the internet charges in dollars

we have

y=2x

This is a proportional relationship between the variables x and y

The slope of the linear function is equal to the constant of proportionality k

k=m=2\frac{\$}{day}

The unit rate is the same that the slope

so

The unit rate is $2 per day

therefore

The unit rate in the equation is 2
