You work at Dave's Donut Shop. Dave has asked you to determine how much each box of a dozen donuts should cost. There are 12 don

slava [35]

A box of donuts would cost: b = 3.84 + 0.18f

First, we have to find the total cost of the donuts.
12 x 0.32 = 3.84

Next, we need to determine the cost of the box. However, we don't know the surface area, just the cost per foot. We can multiply the number of square feet of the box by $0.18 to find the cost.

So our equation could be: b = 3.84 + 0.18f (where f is the surface area of the box in square feet)

Write an equation of the line that passes through the point (2,3) with slope 3.

djyliett [7]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = 3, and the point (2, 3).

Put the value of slope and the coordinates of the given pint (x = 2, y = 3) to the equation of a line:

$3=3(2)+b$

$3=6+b$ subtract 3 from both sides

$-3=b\to b=-3$

Finally:

$y=3x-3$
