I'm not sure what to do for the "arithmetic approach" but for the algebraic approach:
The equation you need to solve would be 5.35x + 182.90 = 750
when you solve it, you would get x = 106, meaning they would have to sell 106 more
Step-by-step explanation:

Explanation
Suppose time Olive is traveling is x hours.
distance=speed×time
Olive's speed=30 miles per hour
time= x hours
Therefore, Olive's distance at time x will be given by:
distance=30×x= 30x
The right equation is:
Miles=30x
