Answer:
1.26885245902 or rounded to $1.27 per pound.
Step-by-step explanation:
you can just divide 3.87/3.05 to see how much each pound costed. if you needed to round to the nearest cent, you would round up to 1.27.... or if not, keep it at 1.26885245902.
then to check your work, you can just multiply (1.26885245902) by (3.05) to get the total amount she had spent.
Answer:
1) Slope: 3; y-intercept: -7
2) Slope: 2/3; y-intercept: 1
Step-by-step explanation:
y = mx + b; m is slope and b is y-intercept
1. y = 3x - 7
The equation is already in slope-intercept form, so you can find the slope and intercept.
Slope: 3
y-intercept: -7
2. y - 1 = 2/3x
For this one, you have to convert this into slope-intercept form (solving for y)
y - 1 = 2/3x
Add 1 to both sides
y - 1 + 1 = 2/3x + 1
y = 2/3x + 1
Now that the equation is in slope-intercept form, you can get the slope and y-intercept.
Slope: 2/3
y-intercept: 1
Answer:
Step-by-step explanation:
The cost function is expressed in dollars as
C(x) = 14980 + 20x
The revenue function is expressed in dollars as
R(x) = 30x
a) At the point of break even, the total cost equals the total revenue. There is neither profit nor loss. Therefore, the the number of units that must be produced and sold to break even would be
14980 + 20x = 30x
30x - 20x = 14980
10x = 14980
x = 1498
1498 mist be produced and sold to break even.
At this level, the dollar amount coming in and going out is
30 × 1498 = $44940
b) Profit = Revenue - cost
P(x) = R(x) - C(x)
P(x) = 30x - (14980 + 20x)
P(x) = 30x - 14980 - 20x
P(x) = 10x - 14980
