Problema Solution
Essay; show all work. Bob’s Barber Shop estimates their gross revenue for the second quarter to be given by the polynomial 9x3 + 4x2 – 6x + 9. The shop estimates their costs for that quarter to be given by 7x2 + 2x + 1. For the second quarter, find and simplify a polynomial that will represent their profit. Note: Profit = Revenue - Costs
Answer provided by our tutors
Revenue:9x3 + 4x2 - 6x + 9
cost: 7x2+2x+1
Profit = revenue - cost
Profit = 9x3 + 4x2 - 6x + 9 -(7x2+2x+1)
Profit = 9x3 + (4-7)x2 -(6+2)x + (9-1)
Profit = 9x3 - 3x2 -8x +8
