Question

the expression c-0.25c can be used to fine the cost of an item on sale for 25% off.which expression below is equivalent to c-0.25c? The answers are 0.75 0.25c 1.25c 0.75c

Answer 1

A) 0.75c

Step-by-step explanation:

~The minuend of this expression is c, the subtrahend is 0.25c~

Let's pretend that "c" is anything, let's say they are cookies.

In the expression, you are taking 0.75 "cookies" away from the 1 "cookie"

So, it is just a simple subtraction problem! Now, solve that equation...

1cookie - 0.25 cookies = 0.75 cookies

or... 1c-0.25=0.75c

I hope this helps!

Answer 2

The correct option is, 0.75c.

How do you calculate a 25% sale?

• Percent Off Price Formula:
• Convert 25% to a decimal by dividing by 100: 25/100 = 0.25.
• Multiply list price by decimal percent: 130*0.25 = 32.50.
• Subtract discount amount from list price: 130 - 32.50 = 97.50.
• With the formula: 130 - (130*(25/100)) = 130 - (130*0.25) = 130 - 32.50 = 97.50.
• 25% off $130 is $97.50.

How do I calculate the sale price of an item given the discount?

• Find the original price (for example $90 ).
• Get the the discount percentage (for example 20% ).
• Calculate the savings: 20% of $90 = $18.
• Subtract the savings from the original price to get the sale price: $90 - $18 = $72.

• The minuend of this expression is c, the subtrahend is 0.25c.
• Let's pretend that "c" is anything, let's say they are cookies.
• In the expression, you are taking 0.75 "cookies" away from the 1 "cookie".
• So, it is just a simple subtraction problem! Now, solve that equation.

1cookie - 0.25 cookies = 0.75 cookies.

or

1c - 0.25 = 0.75c.

Hence, 0.75 are  equivalent to c-0.25c.
