could you help solve this please with steps if possible:

An economist for a sporting goods company estimates the revenue and cost functions for the production of a new snowboard. These functions are respectively given as: R(x) = - x2 + 10x and C(x) = 4x + 5,

where x is the number of snowboards produced, in thousands. The average profit is defined by the function V(x) = P(x)/x, where P(x) is the profit function. Determine the production levels that make the average profit function, V(x), positive.
