The number of chips of different colors in amy's bag is shown below:

8 blue chips
9 pink chips
1 white chip
amy takes out a chip from the bag randomly without looking. she replaces the chip and then takes out another chip from the bag. what is the probability that amy takes out a pink chip in both draws?
9 over 18 multiplied by 8 over 17 equals 72 over 306
9 over 18 plus 8 over 17 equals 297 over 306
9 over 18 multiplied by 9 over 18 equals 81 over 324
9 over 18 plus 9 over 18 equals 18 over 18

B

Step-by-step explanation:

Since Pink Chips are 9, that means you should start would 9/18 and multiply that by 8 since 1 would be the same number. then, you have your answer

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:
