Piano lessons cost $30 per lesson. Find ordered pairs that represent the total cost for x number of lessons.
3, 90 1, 30
"ordered pairs"?
Total cost = $30x
To find the ordered pairs that represent the total cost for x number of piano lessons, you can use the formula:
Total cost = Cost per lesson * Number of lessons
In this case, the cost per lesson is $30. So, the formula can be written as:
Total cost = 30 * x
Now, let's find some ordered pairs for different values of x:
For x = 1:
Total cost = 30 * 1 = $30
So, the ordered pair is (1, 30).
For x = 2:
Total cost = 30 * 2 = $60
So, the ordered pair is (2, 60).
For x = 3:
Total cost = 30 * 3 = $90
So, the ordered pair is (3, 90).
And so on...
You can continue to find more ordered pairs by substituting different values of x.
To find the ordered pairs that represent the total cost for x number of piano lessons, we can use the equation y = 30x, where y represents the total cost and x represents the number of lessons.
To determine the ordered pairs, we can choose different values for x and then calculate the corresponding y values.
Let's choose x values and calculate the corresponding y values:
For x = 1, y = 30(1) = 30. So the first ordered pair is (1, 30).
For x = 2, y = 30(2) = 60. So the second ordered pair is (2, 60).
For x = 3, y = 30(3) = 90. So the third ordered pair is (3, 90).
And so on...
Using this pattern, we can find additional ordered pairs. Here are a few more examples:
For x = 4, y = 30(4) = 120. So the ordered pair is (4, 120).
For x = 5, y = 30(5) = 150. So the ordered pair is (5, 150).
For x = 6, y = 30(6) = 180. So the ordered pair is (6, 180).
In general, any value of x can be used to find the corresponding ordered pair (x, 30x).
