Jeff's graduation picnic will cost $25 if it has 5 attendees. if there are 19 attendees, how much will jeff's graduation picnic cost? solve using unit rates.

Jeff's picnic will cost $95.

Step-by-step explanation:

First, you have to figure out the ratio. The picnic will cost $25 for 5 attendees, so if we divide both numbers by 5, we will find the cost if one person attends. 25 divided by 5 is 5, so our ratio is 1:5. Now, we have to multiply 19 and 5, which is 95, so Jeff's picnic will cost $95.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
