You roll a dice 100 times a 6 = gold, 4 & 5 = silver and 1, 2 & 3 = bronze.
the frequency of gold rolled = 16
the frequency of silver rolled = 35
the frequency of bronze rolled = 49
what is the probability of achieving a gold medal?
what is the probability of achieving a bronze medal?

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:

answer: options
