How many red T-shirts should the manager order PLZ HELP

Use the table showing the numbers of the colors of the last 200 T-shirts sold at a T-shirt shop. The manager of the store wants to order 1800 new T-shirts. How many red T-shirts should the manager order?

35 red t-shirts sold

How many blue T-shirts should the manager order?
55 blue tshirts sold

How many black T-shirts should the manager order?
black tshirts 65 sold

How many more black T-shirts than white T-shirts should the manager order?
30 white thsirts sold

well i will just tell you the numbers okay

red = 341

blue = 535

black = 632

white = 292

well im goin to tell you how and i hope you get it we will add all the t-shirts they sold togather it will be 185
to get the red ones that we should be we will do this

35/185 * 1800 = 340.54 so 341
and so on with the other colors :)

these will all be proportions

200 / 1800 = a / b, where a is the number out of 200 sold, and b is the number expected to be sold out of 1800

rearranging this, a / b = 1 / 9, or b = 9a

so 9 times as many of each should be ordered as were sold from the 200

9(35) = 315 red shirts
9(55) = 495 blue shirts
9(65) = 585 black shirts
9(30) = 270 white shirts

the difference between white and black should be 9(65 - 30) = 9(35) = 315 (which is indeed 585 - 270)
