a phone survey about university tuition has a margin of error of +/-2%.
what is the range of number of people who think tuition is too high at the university if 2004 of the 3421 students said it was and there are about 20,000 students at the university?

a) 11,282 to 11,950 students
b) 11,482 to 11,550 students
c) 11,782 to 11,950 students
d) 11,482 to 11,950 students

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

that one look
