<u>The original price of the sweater was $20.</u>

In this problem, 40% is the amount of discount. We can subtract 40% from 100% because our original price will always be 100%

We can now change this problem to 12 is 60% of what number?

12 is 60% of X

Equation: Y = P% * X

Solving our equation for X

X = Y/P%

X = 12/60%

Converting percent to decimal:

P = 60%/100 = 0.6

X = 12/0.6

X = 20

Therefore, the original price of the sweater was $20

Answer:

The original cost was 20 dollars.

Step-by-step explanation:

$12 represents 60% of the original price.

Set up a proportion

  • 60/100 = 12
  • 100% = x

Cross multiply Reduce 100/100 to 1

60/100 * x = 12 * 100/100

Multiply by 100

60/ 100 * x = 12

Divide by 60

60x = 12*100

60x = 1200                                      

60x/60 = 1200/60

x = 20 dollars.

If m = 5 and n = -2, evaluate 3m - 4n and n2 - m and find the product of the two expressions.
ddd [48]

Hence the correct answer is C) -23

Further explanation:

We have to put the values of m and n into both expression first separately and then multiply the answers.

Given expressions are:

Exp\ 1:3m-4n\\Exp\ 2: n^2-m

The values are:

m=5\\n=-2

Putting the values in expression 1:

3m-4n\\=3(5)-4(-2)\\=15+8\\=23

Putting the values of m and n in second expression

n^2-m\\=(-2)^2-5\\=4-5\\=-1

Multiplying both expressions:

(3m-4n)(n^2-m)=23* (-1)=-23

Hence the correct answer is C) -23
