Question

A chair rental company charges $100 for delivery plus $3 per chair.

You have $410 to spend on chairs. How many can you rent?

Answer 1

I think 3 chairs. (sorry, i read the equation wrong)

Explanation:

Answer 2

103 chairs

Explanation:

cost = fee + cost per chair * number of chairs

410 = 100 + 3*c

Subtract 100 from each side

410-100 = 100+3c-100

310 = 3c

Divide by 3

310/3 = 3c/3

103.3=c

We cannot rent part of a chair so we round down

103 chairs
