The answer would be B
Correct me if I’m wrong
Hello! Lets first start with defining our variables:
a = adult tickets
c = child tickets
Now let’s set up a system of equations:
11a + 8c = 630
c = 1/2a (this can be confusing to some people but the CHILDREN TICKETS = HALF THE ADULT TICKETS)
Ok now we have to solve this:
11a + 8c = 630
c= 1/2a [you can solve this system of equations using substitution!]
11a + 8(1/2a) = 630
11a + 4a = 630
15a = 630
a = 42 (now we know our a value and we can plug that in to find c!)
c = 1/2a
c = 1/2(42)
c = 21
you can check this by plugging in your c and a value into both equations! I hope this helps! :)
Answer: a=42, c=21
Step-by-step explanation:
2/3 - 5/6 * 8
You have to multiply first, then subtract:
-5/6 * 8 = -20/3
Put it back into an equation:
2/3 - 20/3
Simplify:
-18/3
= -6
Answer:
annually
Step-by-step explanation:
Compound interest formula:
A = P(1 + r/n)^(nt)
amount of interest = balance - principal
Try daily:
A = 7775(1 + 0.045/365)^(365 * 14)
A = 14,597.88
This is too much money, so it was compounded less than daily.
Try monthly:
A = 7775(1 + 0.045/12)^(12 * 14)
A = 14,581.23
This is too much money, so it was compounded less than monthly.
Try quarterly:
A = 7775(1 + 0.045/4)^(4 * 14)
A = 14,547.16
This is too much money, so it was compounded less than quarterly.
Try annually:
A = 7775(1 + 0.045/1)^(1 * 14)
A = 14,398.87
This is the correct amount, so it was compounded annually.
Answer: annually
