Let w be the white roses
    3w  be the the red roses
    2w  be the yellow roses

w+3w+2w=48×13
6w=624
w=104 (therefore there are 104 white roses)
red roses = 3w = 104×3=312 
yellow roes= 2w = 104×2=208

104÷13=8 (there are 8 white roses in each bouquet)

therefore, there are 8 roses in each bouquet and 104 white roses if there are 13 bouquet
