The price of an item has been reduced by 65%. The original price was $60. what is the price of the item now?
brilliants [131]
If the price of an item has been reduced by 65%, that means that it used to be 35% higher, and that is the number we have to use in the equation. Here it is:
x - price
35% - how much it got discounted
60 - new price
100% - total percentage

x : 35 = 60 : 100
100x = 60*35 (crossover multiplication)
100x = 2100
x = 2100 / 100
x = 21

The price of the item now is 21$. 


Or you can do it this way:
65% of $60 = 0.65 of 60 = 39; 60 - 39 (how much it was discounted) = 21 (the new price)

Solve the system of equations.
slava [35]

Answer:

B

Step-by-step explanation:

Given the 2 equations

3x - 2y = 6 → (1)

5x + 4y = 32 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the y- term

6x - 4y = 12 → (3)

Add (2) and (3) term by term to eliminate y

11x = 44 ( divide both sides by 11 )

x = 4

Substitute x = 4 into either of the 2 equations and solve for y

Substituting into (2)

5(4) + 4y = 32

20 + 4y = 32 ( subtract 20 from both sides )

4y = 12 ( divide both sides by 4 )

y = 3

Solution is (4, 3 ) → B
