A worker at a clothing company uses 200 buttons to make 50 shirts. At this rate how many buttons would the worker use to make 350 shirts?

You would see how many times 50 can go into 350. 50 can go into 350 7 times. you then take the 200 and multiply it by the same number you multiplied the 50 by. that number was seven. So you would multiply 200 by 7 and get 1400. it took 1400 buttons to make 350 shirts.

1,400 buttons 50x=200 buttons x being the variable for shirts x=4 350 times 4 is equal to 1400
