@ganeshie8

ganeshie8 (ganeshie8):

ratio of white to striple = 10 : 6 = 5 : 3

OpenStudy (anonymous):

Let w = white balls. Cross multiply and solve for w. 10/16 = w/112 16w = 1120 w = 70 Let s = striped 112 - 70 = s 42 = s

is that right

ganeshie8 (ganeshie8):

thats a good try, but a small mistake

ganeshie8 (ganeshie8):

Notice that the balls in the bag will be 128 after adding

OpenStudy (anonymous):

okay

ganeshie8 (ganeshie8):

Oh no, nvm ur work looks good !

OpenStudy (anonymous):

oh ok thanks!

ganeshie8 (ganeshie8):

so after adding 70 white and 42 stripe, there will be a total of 80 white and 48 stripe in the bag

ganeshie8 (ganeshie8):

the ratio will still be 80 : 48 = 10 : 6 as desired. good job !!
