Abox have 5 beads of the same size, but all are different colors. tina draws a bead randomly from the box, notes its color, then puts the bead back in the box. she repeats this 3 times. what is the probability that tina would pick a red bead on the first draw, then a green bead, and finally a red bead again? a. 1/625 b. 1/180 c. 1/150 d. 1/125

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:
