Answer:
there are 13 adults (13 x 9= 117)
there are 6 children (6 x 5.50= 33)
(117 + 33= 150)
Explanation:
if you take 19 and divide it by 150 you would get 0.12666666 and so on then you round that number to the nearest whole and you would have 13 so then you take 9 x 13 and you get 117, so there is your adults and then you would take the 6 leftover and multiply 6 x 5.50 and you get 33 now add 117 and 33 and you get 150
