1/20 Streak
A radio station is giving away a $100 bill to every 30th caller and movie tickets to every
40th caller. Which caller will be the first to win both prizes?

120th caller

Step-by-step explanation:

120 is the common number by 40 and 30. trust me on this I'm really good at this subject in math.

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.

1.35x+1.08y=104.49.

3. solve the system of two equations:
