Question

Answer 1

Answer:

The average between the 2nd and 5th day is 237.50

Answer 2

Answer:

$30/day

Step-by-step explanation:

average rate of change = (s(b)-s(a))/b-a

where s(b) =$310

s(a) = $220

b= 5

a= 2

average rate of change = (310-220)/(5-2)

average rate of change =  90/3

average rate of change = $30/day
