Answer:
533 = 533/1200 will likely pick the beach
Explanation:
Step one add up all the values who chose beach = 50/150 = 1/3
Step two use the new total people asked divided by initial.
1600/150 = x 10.66666667
50 x 10.66666667 = 533.3333335
= 533 rounded down to whole.
Step 4 counter check
50 x 1/3 = 533.333333335
= 533 from 1200 would be the likely total selecting beach.
