Question

# Seven people visited a local restaurant to get some lunch. A burger costs $8 and a bottle of soda costs $2. If all seven people ordered a burger and a soda, find a numerical expression showing the amount of money the restaurant made for this order.

- 7(2 + 8)
- 8(8 + 2)
- 2(8 + 7)
- 7(8 × 2)

Hint:

### Distributive property is the law in which we can solve problems which are in the form a(b+c). To solve this type of problem we just have to multiply a with b and then c which can be written as ab+ ac and then finally add them. It is one of the common formula which is used to solve problems. Here, we have to solve the problem using distributive property.

## The correct answer is: 7(2 + 8)

### In the question it is given that

Number of people visited the local restaurant= 7

Price of a burger=$8

Price of a bottle of soda= $2

We have to find the numerical expression for total amount made by the restaurant.

The total cost = (2 + 8)

Since, seven people ordered a burger and a soda for each.

So, the total number of items ordered is 7(2 + 8).

Therefore, the correct option is a, i.e., 7(2 + 8).

In distributive property, when a factor is to be multiplied with the sum of two numbers, we do not directly add the two numbers and then multiply the sum with the factor. Rather, we multiply both the numbers with the factor differently and then add the multiplication value.
