Answer:
12 million dollars.
Step-by-step explanation:
Let the sales in the first year be x million .
So the sales in the second year were x + 4 million, in the third year were 3(x + 4) and this is 48 million dollars.
So we have the equation 3(x + 4) = 48
3x + 12 = 48
3x = 36
x = 12 million dollars.
Answer: <em>ok so if 60% is under 25 then we can assume 40% is over 25, and then do 40% of 450,000, which is 180,000 .</em>
<em>so we can say that 180,000 people in the town are over 25 years old</em>
Well, it says translate the product of 40 and DISTANCE to the finish line right?
The answer would be 40d
D being the variable for Distance.
7x-y=14 :add 'y' to both sides
7x=14+y :divide both sides by 7
x=(14+y)/7 or x=2+(y/7)
