Let set a = {odd numbers between 0 and 100} and set b = {numbers between 50 and 150 that are evenly divisible by 5}.

what is a ∩ b?

{50, 55, 60, 65, 70, 75, 70, 85, 90, 95}
{55, 65, 75, 85, 95}
{all odd numbers between 1 and 99}
{numbers between 1 and 150 that are evenly divisible by 5}

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:

one set of data has more variation than the other. hope this !
