Step-by-step explanation:
The total cost of the camera is $268.26
A down payment of $12 was paid so he now owes $256.26
Every 6 months Emil has to pay:
256.26 / 6 = 42.71
Therefore, each moth, Emil has to pay $42.71
Total Cost= $0.20x+$42.00
Total Cost= $98.00
$98.00=<span>$0.20x+$42.00
Subtract $42.00 from each side of the equation
$56.00=$0.20x
Divide both sides by $0.20
x=280 miles
Zachary could drive a maximum of 280 miles per day that he rents the car. </span>
