Answer:
c
Step-by-step explanation:
the question gives us c already (the pounds of beans roasted) we know the total should be 280.
we are also given a time period, or a set amount of time in which the beans are roasted at. the coffee shop roasts 280 pounds within 8 hours
because we are told that the <u>rate beans are being roasted at is constant,</u> we know that the amount of beans roasted per hour has to be the same.
so now knowing all of this we know we can evenly divide 280 pounds of coffee by our time limit of 8 hours (280/8) to get the pounds of coffee roasted (280/8 = 35) by each time unit, which in this case <u>t = the number of hours.</u>
so
280 pounds of coffee in total = 35 lbs roasted per hour.
c = 35t
