Substitute 7 for t and do the math.

# A manufacturing company processes raw ore. The number of tons of refined material the company produce during t days using Process A is A(t) = t2 + 2t and using Process B is B(t) = 10t. The company has only 7 days to process ore and must choose 1 of t?

A manufacturing company processes raw ore. The number of tons of refined material

the company can produce during t days using Process A is A(t) = t

2 + 2t and using

Process B is B(t) = 10t. The company has only 7 days to process ore and must choose 1

of the processes. What is the maximum output of refined material, in tons, for this time

period?

A would equal 49 + 14 which is 63 and B would equal 70... Really not that hard
