Question

The total bill of a meal at a restaurant is 25x – 115. Five friends agree to split the cost of the meal equally. What could you do to find the amount that each person must pay? Explain.

Answer 1

Make an equation

Explanation:

First, we make an equation to find out what the bill cost is. Put 25x - 115 in parentheses to indicate "solve this first". Next, assign a value to x. We can say x can be anything, I prefer 2. So now, multiply 25 by 2.

25 x 2 is 50.

Now with 50, subtract 50 from 115.

50 - 115 = 65.

The last step is to divide 65 by 5.

65 / 5 = 13

Lastly, the equation looks like this:

(25x - 115) / 5 = 13

5 friends must pay 13 dollars each.

Hope this helps!
