You work at Dave's Donut Shop. Dave has asked you to determine how much each box of a dozen donuts should cost. There are 12 don
Archy [21]

Answer:

Donuts(b) = 12*b

Step-by-step explanation:

Notice that the question is:

What's an expression to model the number of donuts in b boxes?

We know that we are talking of boxes of a dozen donuts.

We know that in one dozen, we have 12 donuts.

Then if we have b boxes, and in each box we have 12 donuts, we will have a total of b times 12 donuts, the expression is:

Donuts(b) = 12*b

There is a lot of information here that we did not use (like the cost of cardboard and donuts), and that may be there just to distract us, the important thing to do here is:

See what is the thing we want to find (in this case, the number of donuts in b boxes)

Find the relevant information to solve this. (ignore the irrelevant information)

Solve the question.

Evaluate the function f (x)  4 • 7x for x  1 and x = 2. Show your work
SashulF [63]
The function and the first value stated for x are confusing.

Doing some research, I found that the problem is to evaluate the function   f(x)=4.7^x    for x = - 1 and x  2.

The solution is:

1) For x = - 1

f(-1)=4. 7^{-1} =4. (1/7)=4/7

2) For x = 2

f(2)=4.7^2=4(49)=196
