Answer:

the sum of two numbers is 27. their difference is 5. find the number

Step-by-step explanation:

Let x be the first number and y be the second number    ...   so we have

x + y  = 27

x - y  =   5            Adding the equations, we have

2x = 32                Dividing through by 2, we have

x = 16                  And substituting  or x in the first equation, we have

16 + y  = 27         Subtract 16 from both sides  

y = 11

The price for a TV was decreased by 20% and then by 10%. By what percent was the new price lower than the original?
Finger [1]
Let's say the tv was 100$ . Reduced by 20% means the tv is now 100 - 20 = 80% of the original price.

0.8(100) = 80$
Reduced again; by 10% means that it is now 100-10 = 90% of the 80$
0.9(80) = 72$

sale price ÷ original price

72$ / 100$ = 0.72 which is 72% of the original price. Which is a mark down of:
100 - 72 = 28%

The new price is 28% lower than the original price.
