Answer:53 books
Step-by-step explanation:
Answer: Cost of tickets for adults = $22
Cost of tickets for children = $15
Total number of tickets sold = 732
Total receipts = $12,912
Let x be number of adult ticket's sold and y be the number of child ticket's sold.
Therefore, we have:
--------------- equation 1
Also, we have:
Now, let's substitute the value of x:
Now, let's substitute the value of y=456 in equation 1, we have:
Therefore, the number of child ticket's sold is 456 and number of adult ticket's sold is 276
Answer
8(40-y) + 6y =300
320 - 8y + 6y =300
-2y=-20
y=10
This leaves x to be 30.
You should spend 30 minutes on machine 1 and 10 minutes on machine 2.
Step-by-step explanation:
if we distribute 2(2x+5), we'll end up with 4x + 10, so in short, the right-hand-side, is really the left-hand-side in disguise.
and since 4x + 10 = 4x + 10, both equations are equal, meaning in short, the system has an infinite number of solutions.
Answer:
I tried P as the Principle invested: 750, i, as the interest rate per compounding period = 8.2/100 = 0.082 n, number of compounding periods = 2, and t, time is 6 (6 months before July 1 from January 1?) Because I got 1931.03 and it's wrong:
