Raymonds parents will pay for him to take sailboard lessons during the summer. he can take half hour group lessons, or half hour private lessobns. the relationship between cost and number of lessons is linear. table—— lessons| 1, 2 , 3 , 4 , group$ | 55,85,115,145 private| 75,125,175,225 ~find the rate of change and initial value for the private lessons. ~ find the rate and the initial value for the group sessions. ~ compare and contrast the rates of change and the initial values.

The initial fee for both is $25. The rate of change for group is $30 per lesson while private is $50 per lesson.

Step-by-step explanation:

To find the rate of change, we find the difference between two of the same sessions and divide that by the difference between lesson numbers.

Private

For instance, we can subtract for Private lessons the cost for 1 which is $75 with the cost for 2 which is $125. 125-75=50. We divide 50 by 2-1 =1(lesson 2-lesson 1). $50 per lesson. This means the first lesson must be $25 plus a $50 lesson fee. The $25 is the initial value.

Group

For instance, we can subtract for Group lessons the cost for 1 which is $55 with the cost for 2 which is $85. 85-55=30. We divide 30 by 2-1 =1(lesson 2-lesson 1). $30 per lesson. This means the first lesson must be $25 plus a $30 lesson fee. The $25 is the initial value.

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.

happy to

pls mark as brainliest

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
