BearsGirl:

Carmen will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $57 and costs an additional $0.08 per mile driven. The second plan has an initial fee of $50 and costs an additional $0.10 per mile driven.

Yes

Vocaloid:

well I guess we could write an equation for each plan

Vocaloid:

cost = initial fee + (cost per mile)*(number of miles) since the number of miles is not fixed, we can use a variable like m or x to represent the number of miles then just substitute the values from the problem into the equation

Vocaloid:

although there are no other instructions, I would solve for the value of x where one plan becomes more cost-efficient than the other, and include that in your analysis of which plan she should choose
