Answer:
The answer is B.500
Step-by-step explanation:
The original equation containing unknown variables would be 500(t) (with "t" representing the number of days)
So if you fill the variable in with a 2, that means it's been 2 days with the increase of 500 bacteria each day.
That means the initial number of bacteria must be 500.
If it's been 2 days and you want to determine the bacteria number, then multiply 500 by 2 and you get yourself 1000 bacteria.
216.4 is the total cost added up.
198.77 would be the subtraction of the answer above with the hardware supplies but subtraction would be wrong so you'd have to divide, dividing would get you to 0.0814, the you'll have to divide the decimal by 100 giving you 0.0815.
Do the same steps above but with the paint and hardware.
52.91/216.4 gives you 0.244501, rounded up would give you 0.000245.
Add those two totals together to get your answer, 0.081745.
Sorry if I'm wrong. Hope this helps!
