Find the discount.<br> Original price: $0.75<br> Discount: ??<br> Sale price: $0.15
Svetach [21]

Answer:

80%

Step-by-step explanation:

0.75 ⇒ 100%

0.15 ⇒ x%

0.75x = 100·(0.15)

0.75x = 15

x = 15/(0.75)

x = 1500/75

x = 20%

100% - (discount) = x%

100% - (discount) = 20%

discount = 100%-20%

discount = 80%

Simplify the expression -3 ÷ (-2/5 ​
Harlamova29_29 [7]

Answer:

7.5

Step-by-step explanation:

To solve this expression, we can use PEMDAS or order of operations.

<u>Parenthesis</u>

<u>Exponents</u>

<u>Multiplication>Division (Depends on which comes first from left to right)</u>

<u>Addition>Subtraction (See Multiplication>Division)</u>

So First, lets solve the <u>Parenthesis</u>. -2/5=-.4

So now, our equation is -3/-.4

There is no exponents or multiplication, so lets just <u>Divide</u>.

-3/-.4=7.5

The solution is 7.5

Hope this helps!
