Suppose three people ate a meal in a restaurant. the cost of each of their meals is m. one person intends to tip 10%, the second person intends to tip 15%, and the third person intends to tip 20%. which expression represents the total amount that they'll pay? a. 1.1m + 1.15m + 1.2m b. 0.1m + 0.15m + 0.2m c. 1.1m + 2.15m + 3.2m d. 1 + 0.1m + 1 + 0.15m + 1 + 0.2m

For this case we have:

m represents the total cost of each meal. If people do not pay a tip, the total cost to pay would be:

Person 1:

Without tip the cost of your meal is m.

You want to pay 10% tip

m -------------------> 100%

x --------------------> 10%

Thus, its cost will be:

Person 2:

Without tip the cost of your meal is m.

m -------------------> 100%

x --------------------> 15%

Thus, its cost will be:

Person 3:

Without tip the cost of your meal is m.

m -------------------> 100%

x --------------------> 20%

Thus, its cost will be:

Thus, the total cost to pay will be:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

answer:

idk
