Answer:
I think its the lifo method im not sure but i had a question like this in class
Answer:

Step-by-step explanation:
<u>Modeling With Functions</u>
It's a common practice to try to mathematically represent the relation between two or more variables. It allows us to better understand the behavior of the phenomena being observed and, more importantly, to be able to predict future values.
The specific situation stated in the question relates how Taylor buys nail polish for $3.95 each, with a maximum of $30 to spend. If x is the number of nail polish purchased, then the total cost will be

But we know Taylor has a limited budget of $30, so the total cost cannot exceed that amount

Solving the inequality for x


We round down to

Of course, the lower limit of x is 0, because Taylor cannot purchase negative quantities of nail polish
Our model is now complete if the state the limits of x, or its domain

Answer:
The area of the park is 119,966.14 cm if needed to round it would be 119,966 cm.
Step-by-step explanation:
first we would use A=length x width
so a = 614 cm x 212 cm = 130,168 cm
now we find the area of the pond using a= pi x r^2
the diameter is 114 cm so we cut that in half to find the radius which is 57 cm
a = pi x 57^2
a= 3.14 x 3249
a= 10201.86 cm
now we subtract the area of the pond from the whole area
130,168 - 10201.86 = 119,966.14 cm
The area of the park is 119,966.14 cm if needed to round it would be 119,966 cm
That would be vertical angles if they are angle opposite each other when 2 lines intersect.
