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

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.

•  $V\left(m\right)=-16,000m\ -\ 2,000,000$  

•  $V\left(m\right)=-16,000m\ +\ 2,000,000$  

•  $V\left(m\right)=-2,000,000m\ +\ 16,000$  

•  $V\left(m\right)=16,000m\ -\ 2,000,000$

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.
