Question

In a recent survey of 974 voters, 724 indicated that they were in favor of a new city park, while the other 250 voters said that they were opposed.
Using this survey as a basis, if 40,000 citizens vote next week, how many are likely to be opposed to the new park? Round to the nearest whole number.
A) 11.345
B) 9,457
C) 9,927
D) 10,267

Answer 1

250/974 = x/40,000...250 opposed to 974 total = x opposed to 40,000 total
cross multiply because this is a proportion
974x = 10,000,000
x = 10,000,000/974
x = 10266.94 rounds to 10,267 <==
