When you mark up a price, multiply the original price by 1 plus the amount of the mark up as a decimal.
15% = 0.15 + 1 = 1.15
$60 x 1.15 = $69
Answer:
y=3,000(0.92)^x
Step-by-step explanation:
your computer is worth $2, 336.04
Multiple properties of equation.
Assume the smaller one is x, then the other ones will be x+2 and x+4
x(x+2) + 2 = 5(x+4)
x^2 + 2x - 5x - 18 = 0
-> x^2 - 3x - 18 = 0
-> (x-6)(x+3) = 0
-> x = 6 or -3, since x must be positive, then x = 6
So the numbers are: 6, 8, 10
