Step-by-step explanation:
I would write an inequality at this point
The variable would be the amount of hours(x) it would take for the costs to tip the scales
9.75x-10≥7.25x
-10≥-2.5x
4≥x
It would take them 4 hours for the costs to be equal, so anything higher than this would work
Okay organize first and you get
60, 60, 66, 77
even witch means you have to add the middle numbers then divide
60+66=126 divide by two = 63
your answer is B. 63 acres
hope this helped!
