Sophie [7]

Answer:

Part a) x=18\ tickets, y=\$33.50

Part b) y=0.75x+20

Step-by-step explanation:

Let

x------>  the number of ride tickets.

k-----> constant that represent the cost for festival admission

y----> the total cost

we know that

y=0.75x+k

we have that

x=18\ tickets

y=\$33.50

substitute the values

33.50=0.75(18)+k

solve for k

k=33.50-0.75(18)

k=\$20

The linear equation to calculate the cost for anyone who only pays for festival admission and rides is equal to

y=0.75x+20

A 6-inch candle burns down in 12 hours. After how many hours will it have burned<br> 4 inches?
Zielflug [23.3K]

Answer:

8 hours

Step-by-step explanation:

Let's first find how many inches the candle would have burned in 1 hour.

6 in:12 hours

x: 1 hour

We can divide 12 by 12 to get 1. This means we need to divide 6 by 12 to get x

x=1/2 inches

1/2 inches:1 hour

4 inches: x hours

We divide 4 by 1/2 to get 8. 1/2*8=4. This means...

x=1 hour*8=8 hours
