Top performing college students in a known university plan to put up a tutorial center for high school students. They agree that the
price will be +500 if a student will be tutored for 2 hours. However,
the price will be $700 if a student will be tutored for 3 hours. If
the relationship between the cost and time is linear, what is the
price when the student will be tutored for 4 hours? How long can
a student be tutored for *1,000?

  a) $900

  b) 4 1/2 hours

Step-by-step explanation:

The price goes up by $200 for the additional hour between 2 and 3 hours of tutoring. If the relationship is linear, it will go up $200 again, from $700 to $900, as the time goes up from 3 hours to 4 hours.

  The cost for 4 hours is $900.

The session costing $1000 is only $100 more than a 4-hour session. Since the rate is $200 per hour, that $100 will pay for 1/2 hour more than 4.

  A student can be tutored 4 1/2 hours for $1000.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
