Question

A group of 5 friends is out to dinner. Each of the friends will order the dinner special, and they have a coupon for $10 off the entire bill. Which equation can be used to find the total cost of all the dinners ofter the coupon is applied? 50 - 100 50 + 10 = C 100 + 5 = 0 100 - 5 =

Answer 1

Let the cost of the dinner be d

Let the total cost be C

Since, a group of five friends are going for dinner

Therefore, all the five friends will be paying

5 x cost of the dinner = 5d Before the coupon

If they have $10 off the entire bill

This implies that we will substracty $10 from the total bill

Hence, the total cost is given as

C = 5d - 10

The answer is C = 5d - 10
