Piano lessons cost $30 per lesson. Find ordered pairs that represent the total cost for x number of lessons.
(–1,–30)
(0,30)
(1,30)
(1.5,50)
(3,90)
Assuming that the first number is the number of lessons, (1,30) and (3,90). (-1,-30) might apply, if receiving a refund for a missed lesson.
m, klm hkjnm,jnmkjmnk,
it is (1,30) (3,90) i'm right trust me
To find the ordered pairs that represent the total cost for x number of piano lessons, we need to understand the relationship between the number of lessons and the cost.
In this scenario, the cost of piano lessons is $30 per lesson. This means that for every lesson, the cost is $30. Therefore, we can calculate the total cost by multiplying the number of lessons (x) by the cost per lesson ($30).
Using this information, we can create the ordered pairs by combining the number of lessons (x) with the total cost. Let's calculate the total cost for each given number of lessons:
For the first pair (–1, –30):
Total cost = number of lessons * cost per lesson
Total cost = -1 * $30
Total cost = - $30
So, the ordered pair is (-1, -30).
For the second pair (0, 30):
Total cost = number of lessons * cost per lesson
Total cost = 0 * $30
Total cost = $0
So, the ordered pair is (0, 30).
For the third pair (1, 30):
Total cost = number of lessons * cost per lesson
Total cost = 1 * $30
Total cost = $30
So, the ordered pair is (1, 30).
For the fourth pair (1.5, 50):
Total cost = number of lessons * cost per lesson
Total cost = 1.5 * $30
Total cost = $45
So, the ordered pair is (1.5, 45).
For the fifth pair (3, 90):
Total cost = number of lessons * cost per lesson
Total cost = 3 * $30
Total cost = $90
So, the ordered pair is (3, 90).
Therefore, the ordered pairs representing the total cost for different numbers of piano lessons are:
(-1, -30), (0, 30), (1, 30), (1.5, 45), and (3, 90).
