[Part A]
company A company B
A=3h+75 B=2h+85
definition of variables
A=company A
B=company B
h=number of hours used
[Part B]
company A would charge less for 5 hours
justification
company A company B
A=3(5)+75 B=2(5)+85
A=15+75 B=10+85
A=90 B=90
[Part C]
By using the services of company A instead of company B to rent a truck for three hours you save 7 dollars.
company A: A=3(3)+75 = 9+75= 84
company B: B=2(3)+85 = 6+85 = 91
difference: 91-84= 7
I believe the answer you are looking for is 2 angles
<h3>Option C</h3><h3>The average rate of the reaction over the entire course of the reaction is:

</h3>
<em><u>Solution:</u></em>
Average rate is the ratio of concentration change to the time taken for the change

The concentration of the reactants changes 1.8 M to 0.6 M
here, the time interval given is 0 to 580 sec
Therefore,

Thus option C is correct
