3(n+5) < 3/4(n)
The three is multiplied by n+5. Whenever you see "is equal to/greater/less than," that is where you put your =, >, or < signs. Your variable, "n" represents the number. So three-fourths of the number is the same as multiplying the number by three-fourths.
Use the FOIL method: First, Outside, Inside, Last
3x(2x) = 6x²
3x(-4) = -12x
3(2x) = 6x
3(-4) = -12
6x² -12x + 6x-12
Combine like terms
-12x + 6x = -6x
6x² - 6x - 12 is your answer

Answer:
x = 11
Step-by-step explanation:
sides are proportional so you can set up a proportional and cross-multiply:
JL is to PQ as LK is to QR
x/22 = 8/16
x/22 = 1/2
2x = 22
x = 11
1. Since it's increased by 40% it would be 140%
2. It would be $294
