Answer:
(a) This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
Step-by-step explanation:
The equation of direct variation is ...
y = kx
for some constant k. Here, we have x in hours and y in dollars. We can see if k is constant for the values given in the table.
__
<h3>constant of variation</h3>
Solving the direct variation formula for k, we have ...
k = y/x
Using the table values, we can see if this is constant:
k = dollars/hour = 10/2 = 20/4 = 30/6 = 40/8 = 5
The "rate of change" is constant at $5 per hour.
The function represents direct variation because it passes through the origin and has a constant rate of change of $5 per hour.

Step-by-step explanation:
Pears Cameron has = 6 pounds
roasted-pears recipe per batch = 13 pounds
How many batches can he make?
Number of batches of roasted-pear = Pears Cameron has / roasted-pears recipe per batch
= 6 pounds / 13 pounds
= 0.4615384615384 pounds
Approximately,
Number of batches of roasted-pear = 0.46 pounds

Step-by-step explanation:
the question has end to end answer
deposit of $1644.50 is (gain)
check written and deposit are (loses) subtracted
so total of 3 checks :- 190$ + 45$ + 7.50$ = 242.50$
total of 4 debit cards :- 30$ + 5.59$ + 7.20$ + 21.30$ = 64.09$
total lose amount ( credits + debits ) = 242.50 $ + 64.09$ = 306.59$
Ending balance = Total amount - total loses =
1644.50$ - 306.59 $ = 1337.91$
