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

We can divide the total bill amount by the number of friends. This gives that the amount payable by each person is (5x - 23).

Step-by-step explanation:

Here, total bill amount = 25x - 115

In order to find the amount that each of the five friends must pay equally, we divide the total bill amount by the number of friends.

So, each person must pay (25x - 115) ÷ 5

= {5 (5x - 23)} ÷ 5

• HINT: We have take 5 common from both 5x and 115.
• Now we divide the common 5 by the divisor 5.
• This results: 5 ÷ 5 = 1.

= 5x - 23

Answer 2

Answer:

Factor the GCF of five out of the total bill. Divide both terms of the expression by 5. The result is 5x – 23, which is the expression that can be used to find the amount each person pays.
