Answer:
Part A: 3 3/4 Part B: 5 1/4
Step-by-step explanation:
Part A: 3/4x5=3 3/4
Part B: 3 3/4 +1 2/4=5 1/4
If we know the cost of a ticket is $7, we can then write an equation in slope-intercept form for the amount it will cost to buy any amount of tickets.
If we denote x as the amount of tickets purchased, and c as the total cost, we can write the equation:

Since we can vary the amount of tickets purchased independently of the total amount, x (the amount of tickets purchased) will be the independent variable.
However, since y (the total cost) is directly dependent on the amount of tickets that are purchased, c is the dependent variable.
Answer:
You taught for 4 hours
Step-by-step explanation:
Let this number of hours be x. Then:
Total earned = $20 + ($8/hr)x
Equate this to $52 and then solve the resulting equation for x:
20 + 8x = 52
Then 8x = 32, and x = 4. You taught for 4 hours.
