A group of three restaurant patrons order the same meal and drink, leaving an 18% tip. Identify the composition of the two functions, that gives you the cost for all of the meals, including the tip.

Oa

g(f(x)) = 1.18x

Ob

f(g(x)) = 3.54 + x

g(f(x)) = 3.54x

Od

f(g(x)) = 1.18 + x

g(f(x)) = 3.54x

Step-by-step explanation:

We are told that there a group of 3 restaurants patrons order the same meal and drink.

Thus;

f(x) = 3x

Where x is the cost of one meal

Now, we are told that they leave an 18% tip. This means they paid an additional 18% of their food cost.

Thus, total they paid is 118% of the food cost or expressed as a function is;

g(x) = 1.18x

Now, we want to Identify the composition of the two functions, that gives you the cost for all of the meals, including the tip.

This will be;

g(f(x)) = 1.18 * 3x

g(f(x)) = 3.54x

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
