Explain the difference between 25% off $300 and 25% of $300.

25% off means the cost to the customer will be 225

25% of means take 25% * 300 (which is 75) and that is the going price.

Step-by-step explanation:

25% off 300 means that you take 300, and find out what 25% of that is.

25/100 * 300 = 75

Now that means that the customer gets to take 25% off the selling price which is 300 - 75 = 225.

The new price is $225.00

25% of 300 has an entirely different meaning. It means that "what is 25% times 300"

That's the same 75 dollars. Only this time, that's the answer. Of means multiply.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
