You are given a price-demand function, p(x) = −5x + 90, where x is the number of items made and sold and p(x) is the price per item (in dollars). Write the revenue function, R(x), for the sale of x items.
Added by Felix C.
Step 1
The revenue function \( R(x) \) is calculated by multiplying the price per item \( p(x) \) by the number of items sold \( x \). Show more…
