A business breaks even when the production costs are equal to the revenue. The expression 120 + 4x represents the cost of producing z items. The selling price is $5 for each item. Write an expression for the revenue generated by selling x items. How many items would you need to sell to break even? Write an equation and solve it. Enter the coIrect answers in the boxes. Hint Expression for revenue: Equation: Items needed to sell to break

Step-by-step explanation:

We know that revenue= production=break even point

given that the expression for cost of production is

z=120+4x1 cost of production

where x is the number of items produced

also the selling price per item is $5

The revenue generated from the production of x items is(let the revenue be y)

y=5x2 revenue equation

break-even is when y=z

120+4x=5x

solving for x we have

120=5x-4x

120=x

x=120items

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
