Show why these calculations are equivalent in general. (Hint: Write an expression for finding an amount A minus n% of A. Write another expression for finding (100- n)% of A, and then use algebra to show that these two expressions are the same.)

step-by-step explanation:

the answer is 128

i'm a sophomore in connections, i'd recommend checking on jishka.com they have a large range of questions and answers from our school.

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2
