In a survey, four out of five people surveyed preferred creamy over chunky peanut butter. 120 people are shopping at the grocery
elixir [45]

Answer: Around 96 people would prefer creamy peanut butter.

Step-by-step explanation:

In the survey was found that 4 out of 5 preferred creamy over chunky peanut butter.

Then the relative frequency is:

4/5 = 0.8 prefer creamy peanut butter.

And we can assume that:

1/5 = 0.2 prefer chunky peanut butter.

We also could multiply these numbers by 100% to obtain the percentage forms:

0.8*100% = 80%

0.2*100% = 20%

Now, if there are 120 people in the grocery store, we can expect that the 80% will prefer creamy peanut butter.

Then we can expect that the number of people that prefers creamy peanut butter is:

N = (80%/100%)*120 = 0.8*120 = 96

Around 96 people would prefer creamy peanut butter.

A salesperson's commission rate is 4%. What is the commission from the sale of $32,000 worth of furnaces? Use pencil and paper.
Delvig [45]

Answer:

Step-by-step explanation:

commission from sale of $32,000 = $32,000 x 4% = $1,280

Suppose sales would double, comission would be doubled too.

Assume sales be S and commission be C

C = S * 4% (they have a linear positive relation)

if S double to 2S, new commission = (2S)*4% = 2*(S*4%) = 2 (old commission)
