Answer:
a) Here x represent number of ride tickets
z represent admission fees. = $20
y represent total cost.
Step-by-step explanation:
a) Here x represent number of ride tickets
z represent admission fees.
y represent total cost.
b) Given that,
$0.75 per ticket for the rides.
Number of tickets (x) = 18
Total spent (y) = $33.50
Total cost = (number of tickets)*(price per ticket) + admission fees
y =0.75x + a
We can calculate the cost for anyone who only pays for festival admission and rides.
c)
Put y = 33.50
x = 18
33.50 = 0.75*18 + a
33.50 = 13.5 + a
Solve for a,
Subtract 13.50 both the side
33.50 - 13.50 = 13.50-13.50 + a
20 = a
So, admission cost (a) = $20
The formula to find the area of this circle is:
A = pi(r^2)
A = 3.14(3.5^2)
A = 3.14(12.25)
A= 38.465 cm
