5 squared -4 over 5 + 2

A pair of jeans is on sale for 25% off the regular price. Write the algebraic expression for the sale price. If the original price of the jeans was $40, evaluate the expression to find the sales price.

My answer is s = p - 0.25 p; $30

1st question:

not sure if you mean: 5^2 - 4/5 + 2
or
(5^2 - 4)/5 + 2
or
....
can you see why you might want to use brackets to establish the correct order of operation
so, if 5^2 - 4/5 + 2
then 25 - 4/5 + 2 = 27-4/5 = 131/5

if (5^2 - 4)/5 + 2
then (25-4)/5 + 2
= 21/5 + 2
= 31/5

sale price = 40 - .25(40) = 30

or
sale price = .75(40) = 30

(your statement of s = p - .25 makes no sense)

To simplify the expression, we'll follow the order of operations (also known as PEMDAS) and combine like terms.

First, let's calculate 5 squared:
5 squared = 5 * 5 = 25

Next, we have -4 over 5, which is an improper fraction. To convert it to a mixed number, we divide the numerator (-4) by the denominator (5).
-4 ÷ 5 = -0.8

Now, we'll rewrite the expression by substituting the calculated values:
25 - 0.8 + 2

To continue simplifying, we add the numbers:
25 - 0.8 = 24.2
24.2 + 2 = 26.2

So, the simplified expression is 26.2.
