Question 1 of 10
On a vacation in Puerto Rico, Rose jumped off a cliff into a river in El Yunque Forest Reserve. Her
height as a function of time could be modeled by the function h(c) -16t? + 16 + 480, where t is
the time after jumping in seconds and h is the height in feet. How many seconds did it take Rose to
hit the water? Round your answer to the nearest hundredth.
seconds

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:
