Problem 20: In the year 2001, product A was sold for $300 per unit making a gross profit of 20% on sales. The total production cost was made up of 25% of direct material, 40% of direct labor, and 35% of factory overhead. Due to general rise in prices in 2002, the selling price of the product increased by 15%. The cost of production has also increased resulting in increase of Material, Labor, and factory overhead costs by 10%, 15%, and 12% respectively. What will be the gross profit per unit in 2002?

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

answer: 3.26019516

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
