I'll give you a question, please answer with step-by-step reasoning process.
Five friends eat at a fast-food chain and order the following: 5 pieces of hamburger that cost $3 each; 4 sets of French fries that cost $1.20; 5 cups of soda that cost $0.5 each; and 1 platter of spaghetti that cost $2.7. How much will each of them pay if they will split the bill equally?

5
The cost of 5 pieces of hamburger is $3 x 5 = $15.

The cost of 4 sets of French fries is $1.

20 x 4 = $4.

80.

The cost of 5 cups of soda is $0.

5 x 5 = $2.

50.

So their total bill is $15 + $4.

80 + $2.

50 + $2.

7 = $25.

Hence, each of the five friends will contribute $25 / 5 = $5.

.

The answer: 5
