Question

Four friends go out for lunch three of them Order cheeseburgers at a cost of 4.75each one friend orders. A slice of pizza for 2.55 and all of them purchase a drink for 1.20each they decided to split the bill equally how much is each friends share

Answer 1

Individual bill = 5.4 units

Step-by-step explanation:

Given the following data;

Total number of friends = 4

• Cost of cheeseburger, C = 4.75
• Quantity of cheeseburger, Q= 3
• Slice of pizza, P = 2.55
• Cost of drink, D = 1.20
• Quantity of drinks, Q = 4

To find how much each would pay;

First of all, we would calculate the total cost incurred by the four friends using the mathematical expression;

Total cost = CQ + P + DQ

Total cost = (4.75 * 3) + 2.55 + (1.20 * 4)

Total cost = 14.25 + 2.55 + 4.8

Total cost = 21.6

Since they are sharing the bill equally, we would divide the cost by the total number of friends.

`Individual \; bill = \frac {Total \; cost}{Number \; of \; friends}`

Substituting the values into the formula, we have;

`Individual \; bill = \frac {21.6}{4}`

Individual bill = 5.4 units
