I don’t understand how to get the answer

  200 miles

Step-by-step explanation:

The way you're expected to solve this is to write an expression for the rental cost paid by each person. Since you want to find the number of miles that makes the rental costs the same, set those two expressions equal to each other and solve for m.

Albert's rental cost (in dollars) for driving m miles in one day is ...

  A = 35 + 0.15m

Makayla's rental cost for driving m miles in one day is ...

  M = 45 +0.10m

To make the costs the same, we set these equal to each other:

  A = M

  35 +0.15m = 45 +0.10 m

  35 + 0.05m = 45 . . . . . . . . . . subtract 0.10m from both sides

  0.05m = 10 . . . . . . . . . . . . . . . subtract 35 from both sides

  m = 200 . . . . . . . . . . . . . . . . . divide by 0.05

If they spend the same on their rentals, Albert and Makayla both drive 200 miles.
