Explanation / Answer

Given, weekly fixed fost fo rent and utilities = $1500

labor and material cost per each phone = $ 18.50

labor and material cost per x phones = 18.5x

a) Cell Pro's weekly total cost = fixed cost + variable cost

here fixed cost is the rent, utilities and the variable cost is the cost incurred on no.of phones produced.

so, Total Cost = $18.5x + $1500

b) Revenue = selling price x no.of phones sold per week

So, Revenue = $45.50x

c) Weekly Profit = Total revenue-Total cost

implies $45.50x - ($18.5x + $1500)

Profit = $27x - $1500
