Juan starts a new coffee shop. the table shows the coffee sales at his shop for the first 5 days.

what is the average rate of change in the sales per day between the 2nd and 5th day?

$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

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
