Answer:
210 orange candles
280 blue candles
Step-by-step explanation:
x = blue candles
y = orange candles
y = 0.75x
x + y = 490
x + 0.75x = 490
1.75x = 490
x = 280
280 + y = 490
y = 210
Answer:
9 hours
Step-by-step explanation:
First we have to calculate how many eggs she can collect in an hour. All we have to do to do this is divide 80 by 2, as if she can collect 80 in 2 hours, in one hour, half of the time, she can collect have of the eggs. This means that she can collect 40 eggs in one hour.
Now all we have to do is divide how many eggs she wants to collect by how many she can collect per hour, which will give how many hours it will take. In this case 360/40=9, so it will take her 9 hours.
Answer:
$59
Step-by-step explanation:
Let the revenue will be maximum when $ x is increased in the ticket price.
So, the final ticket price is $(18 + x) and attendance in the concert will be (500 - 5x)
So, revenue R = (18 + x) (500 - 5x) = 9000 + 410x - 5x².......... (1)
Condition for R to be maximum is 
So, differentiating equation (1) with respect to x on both sides
⇒ x = 41
So, the ticket price for maximum revenue is $(18 + 41) = $59 (Answer)
I think this has to do with P=IRT where P is the amount, I is the interest amount R is the interest rate and T is the time so we plug in the numbers we have and get $30 for interest amount so our total amount would be 530.
