$3.99+$3.99=$7.98
$4.49+$4.49=$8.98
$7.98+$8.78+$4.99=$21.75
$50.00$21.75=$28.25.
You should receive $28.25 in change.
This task has not been easy.
Yes you do , i learned pythagorean theorem last year in pre-algebra
Answer:
Two packs of buns and three hotdog packages
Step-by-step explanation:
We have the following function:

So if we graph this function we will get the Figure below. Thus, let's study both the equation and the graph to get some conclusions. Therefore, we can assure these statements:
First. The function is defined only for

as shown in the Figure. This is also true because of

where

must be greater (or equal) than zero.
Second. The range of the function are the values of

.
Third. If

creases then

always creases, too.
