Answer:
Individual bill = 5.4 units
Explanation:
Given the following data;
Total number of friends = 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.
[tex] Individual \; bill = \frac {Total \; cost}{Number \; of \; friends} [/tex]
Substituting the values into the formula, we have;
[tex] Individual \; bill = \frac {21.6}{4} [/tex]
Individual bill = 5.4 units
