Answer:
$247.50
Step-by-step explanation:
330 decrease 25% =
330 × (1 - 25%) = 330 × (1 - 0.25) = 247.5
f(x) = 2(x+8)
replace f(x) with 12 and then solve for x:
12 = 2(x +8)
Use the distributive Property on the right side:
12 = 2x +16
Subtract 16 from each side:
-4 - 2x
Divide both sides by 2:
x = -4 / 2
x = -2
