Tonya and Emily each have an online jewelry store. Let T represent the amount of money Tonya earns daily, and let E represent the amount of money Emily earns daily. The mean difference, D = T-E, of the amount of money that Tonya
and Emily earn on a typical day is $312. What is the correct interpretation of this value?
O On average, Tonya earns $312 daily.
Emily is earning $312 per customer, on average.
Tonya and Emily are each earning $312 on a typical customer.
On average, Tonya makes $312 more than Emily on a typical day.

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

the answer to 1/4x+5/3x-4=2-1/12x is x=3
