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

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

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

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

we have that

solve for x

Answer:
Step-by-step explanation:
<u>Given trinomial</u>
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>
1 hour = 60 minutes
2 hours = 120 minutes
3 hours = 180 minutes
4 hours = 240 minutes
5 hours = 300 minutes
(5 hours) x (60 minutes / 1hour) = 300 minutes
5 x 60 = 300
