7/10 + 4/5

  • Make 4/5 have a common denominator with 7/10 by multiplying 4/5 by 2/2.
  • 4/5 * 2/2 = 8/10

Add 7/10 and 8/10.

  • 7/10 + 8/10 = 15/10

Justin will rent a car for the weekend. He can choose one or two plans. The first plan has an initial fee of $75 and cost an add
murzikaleks [220]
To find when their costs will be same, we can set them equal to each other.

While writing the equation, we need to take into account that one plan has a base payment of 75 no matter how much Justin drove. And there are changeable values which are effected by the x, the miles driven by Justin.

So the equation is 0.80x + 75 = 0.90x

When we subtract 0.80x from both sides: 0.10 \times = 75

Divide both sides by 0.1: x = 750

He needs to drive 750 miles to make 2 plans' cost equal.
