Normaly you would call customer service for serveys and they dont ask for them
Answer:
i hope this helps
Step-by-step explanation:
if you have 100 people in the room and you interviewed all of them, (for number 6). that means that 70% of these people ate breakfast
70% of the total amount of people you interviewed is 70. That means that 70 people you interviewed, eat breakfast.
Then it also says, "of those 70% of people, 25% eat cereal"
That means 25% of those 70 people eat cereal, or 1/4 of that population does.
0.25 * 70 = 17.5. (of course you cannot have part of a person, but this is an example)
and of the 17.5 people, 30% of them eats it with extra sugar.
so 30% of 17.5 people is 5.25.
that means that there are 5.25 people who eat cereal with extra sugar.
i hope this helps, it took a while for me to try to help with this
i noticed that you made a mistake. the amount of people that eat cereal is 25% of 70% of the people. that means you have to find 0.25 of 0.7 <--- (you multiply not divide)
(0.25x 0.7) = 0.175
B. Because the divisor, 4.2, has only value in the ones and tenths places, so we only have to multiply by 10 to get to 42, which is the whole number you need.
