A car rental agency advertised renting a luxury full sized car for 29.95 per day and 0.49 per mile if you rent this car for 2 days how many whole miles can you drive if you only have 200$ to spend

285

9

342

100

The answer:

285

So you make an expression 29.95x + 0.49y = 200

So first you times 29.95 to 2 and you will get 59.9

Then you subtract that from 200 and you will get 140.1

Then you didvide that by 0.49 and you will get 285.9183673469388.

Round it backwards and you'll get 285.
