A pet supply company uses the equation below to calculate the profit they make from selling dog leashes where x represents the number of leashes sold an p(x) represents the profit in dollars. P(x)= -3t^2+78t-9

Find the number of leashes which need to be sold to maximize the profit.

Find the maximum profit.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
