...found to be R(x) = x ?400-x? Hello,
Could someone help explain step by step on how to solve this, thanks in advance
The revenue gained from the sale of x thousands of units of a certain commodity is found to be
R(x) = x sqrt(400-x). (a) Use differentials to estimate the change in revenue as sales move from 39000
to 39100 units (hint: note that x is not 39000 or 39100!). (b) Find the true change in revenue. (c) Find
the relative change in revenue and the percentage change (note – this requires the formulas from 3.5).
