High interest rates make it difficult for people to pay off credit card debt in a reasonable period of time. the interest i (in dollars) paid on a $10,000 debt over 3 years when the interest rate is r% can be approximated by the equation shown below.â i 175.393 + 0.663= r if the credit card interest rate is 23.9%, find the amount of interest paid during the 3 years.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

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
