The temperature in Lucy's refrigerator is 2.74 degrees celious.the temperature in the freezer section of her refrigerator is -19.4 degrees celcious. How much colder is the freezer temperature

Answers

you have to find the difference between temperatures of refrigerator and freezer.

2.74 - (-19.4) = 2.74+19.4 = 22.14 degrees Celsius

so freezer is 22.14 degrees colder

2.74 - (-19.4) = 22.14, so the freezer is 22.14°c colder. I hope that helps!

Find the original price. Discount: 20% Sale price: $75

Answers

The original price of the item is given by the equation A = $ 93.75

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the original price of the item be represented as A

Now , the equation will be

The discount percentage of the item = 20 %

The discounted sale price of the item = $ 75

So , original price - ( 20/100 ) original price = discounted price

Substituting the values in the equation , we get

A - ( 20/100 )A = 75

( 80/100 )A = 75

Multiply by 100 on both sides of the equation , we get

80A = 7500

Divide by 80 on both sides of the equation , we get

A = $ 93.75

Hence , the original price is $ 93.75

How I solve these is to divide the sale price by the current percentage of the price. Since is is only 80% of the original price, I would divide $75 by 80, which will give you the amount that is equal to 1%. then multiply that number by 100 and it will give you the full cost of the item.

$75 / 80% = 0.9375
0.9375 x 100 = $90.75
