What two equations would you use to solve this word problem?

Goran will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $53 and costs an additional $0.11 per mile driven. The second plan has an initial fee of $40 and costs an additional $0.13 per mile driven.

• y= 53 + 11x

  and

  y = 40 + 13x

• y= 53 + 40

  and

  y = 0.11x + 0.13x

• y= 53 + 0.13x

  and

  y = 40 + 0.11x

• y= 53 + 0.11x

  and

  y = 40 + 0.13x

What two equations would you use to solve thios word problem?

A phone company offers two monthly plans. Plan A costs $28 plus an additional $0.12 for each minute of calls. Plan B has no initial fee but costs $0.17 for each minute of calls.

• y= 28 + 0.12x

  and

  y = 0.17x

• y= 0.12x

  and

  y = 28 + 0.17x

• y= 28x

  and

  y = 0.12x + 0.17x

• y= 28 + 0.17x

  and

  y = 0.12x

• add 0.11 and 0.13

• subtract 0.11x from both sides

• add 0.13x to both sides

• add 53 and 40
