A buffet costs $15 plus $2 for each drink. Which function gives the total cost?

A. c(d)=2+15d
B. c(d)=17+d
C. c(d)=17d
D. c(d)=15+2d

D.

Step-by-step explanation:

The buffet by itself is $15, so that will be a number by itself, since it isn't changed by any variables. (you can rule out a, b, and c by this point).

Since it's $2 for each drink, this would require a variable since the price would fluctuate depending on the number of drinks.

Therefore, your function should look like this:

what is the graph

step-by-step explanation:

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
