The price of a video game increases by 20%, then decreases by 10%. If the final price is $46.98,
Elena-2011 [213]

Answer:

The original price was $43.50

Step-by-step explanation:

Let

x ----> the original price of a video game

we know that

1) The price of a video game increases by 20%

so

100\%+20\%=120\%=120/100=1.20

The final price is equal to the original price multiplied by 1.20

so

1.20x

2) The price of a video game decreases by 10%

so

100\%-10\%=90\%=90/100=0.90

The final price is equal to the price at this moment multiplied by 0.90

so

0.90(1.20x)=1.08x

we have that

1.08x=46.98

solve for x

x=46.98/1.08\\x=\$43.50

PLEASE HELP! Is the following trinomial factorable why or why not<br> h=-4(4t^(2)-9t+2)
sineoko [7]

Answer:

  • h = -4(t - 2)(4t - 1)

Step-by-step explanation:

<u>Given trinomial</u>

  • h= -4(4t² - 9t + 2)

Let's try to factor 4t² - 9t + 2

<u>First find it's zeros:</u>

  • t = (9 ± √9² - 4*4*2)/(2*4)
  • t = (9 ± √81 - 32)/8
  • t = (9 ± 7)/8
  • t = 2 and t = 1/4

<u>So yes, it is factorable:</u>

  • 4t² - 9t + 2 = 4(t - 2)(t - 1/4)
  • or
  • 4t² - 9t + 2 = (t - 2)(4t - 1)

<u>The given trinomial factored:</u>

  • h = -4(t - 2)(4t - 1)

5 hours = 300 minutes

(5 hours) x (60 minutes / 1hour)  =  300 minutes
