David bought an industrial mixer for his dessert business. The machine cost $ 2,000,000. They informed him that in case he wanted to sell it and buy a new one, the machine was depreciating $ 16,000 per month. Write the function that represents the situations of the value of the machine V and the numbers of months m.

V ( m ) = − 16 , 000 m + 2 , 000 , 000 V\left(m\right)=-16,000m\ +\ 2,000,000 V ( m ) = − 1 6 , 0 0 0 m + 2 , 0 0 0 , 0 0 0

V ( m ) = − 16 , 000 m − 2 , 000 , 000 V\left(m\right)=-16,000m\ -\ 2,000,000 V ( m ) = − 1 6 , 0 0 0 m − 2 , 0 0 0 , 0 0 0

V ( m ) = − 2 , 000 , 000 m + 16 , 000 V\left(m\right)=-2,000,000m\ +\ 16,000 V ( m ) = − 2 , 0 0 0 , 0 0 0 m + 1 6 , 0 0 0

V ( m ) = 16 , 000 m − 2 , 000 , 000 V\left(m\right)=16,000m\ -\ 2,000,000 V ( m ) = 1 6 , 0 0 0 m − 2 , 0 0 0 , 0 0 0

David bought an industrial mixer for his dessert business. The machine cost $ 2,000,000. They informed him that in case he wanted to sell it and buy a new one, the machine was depreciating $ 16,000 per month. If the seller tells David that he receives the machine for $ 1,255,000 in 4 years, as credit for a new one. Is David getting a good offer? Explain.

Yes, In four year the cost of the machine will be $1,232,000. So this is a good offer.

No, In four year the cost of the machine will be $1,432,000. So this isn't a good offer.

Yes, he is going to receive 25% more of the the real value of the machine after four years of use.

No, He is going to receive 10% less of the real value of the machine after four years of use.

The total cost function is the variable cost times the number of unit produce plus the fixed cost. Ale & Vale's Brownies Company has a fixed cost of $80,000 and a variable cost of $700. Write the function and find how many brownies would they have to sell to have a total cost of $185,000?

C(x)=700x+80,000; They would have to sell 150 brownies.

C(x)=700x-80,000; They would have to sell 100 brownies.

C(x)=80,000x+700; They would have to sell 150 brownies.

C(x)=-700x+80,000; They would have to sell 250 brownies.

Kevin's car needed repairs. At Keinner's Luxury Cars charged him $640 for the parts and an additional $148 for each hour for labor. Write an equation that models this situation and tell How much money did Kevin have to pay if the mechanic worked 6 hours in his car?

y = 148x + 640; Kevin paid $1,528

y = 640x + 148; Kevin paid $3,988

y = 148x - 640; Kevin paid $248

Find the equation of a line parallel to 4x - y = 2, that goes through (-2,-5).

4 x − y = − 3 4x-y=-3 4 x − y = − 3

4 x + y = − 3 4x+y=-3 4 x + y = − 3

4 x − y = 3 4x-y=3 4 x − y = 3

Find the equation to the line perpendicular to y = − 2 3 x + 4 y=-\frac{2}{3}x+4 y = − 3 2 x + 4 that goes through (8, 1).

y = 3 2 x − 11 y=\frac{3}{2}x-11 y = 2 3 x − 1 1

y = 3 2 x + 11 y=\frac{3}{2}x+11 y = 2 3 x + 1 1

y = − 3 2 x − 11 y=-\frac{3}{2}x-11 y = − 2 3 x − 1 1

y = − 3 2 x + 11 y=-\frac{3}{2}x+11 y = − 2 3 x + 1 1

A driving range charges $4 to rent a golf club plus $2.75 for every bucket of golf balls you hit. Write an equation that shows the total cost c of hitting b buckets of golf balls.

c = 2.75b + 4

c = 2.75b

c = 4b- 2.75

c = 2.75b - 4
