Going against the current, a boat takes 6 hours to make a 120-mile trip. When the boat travels with the current on the return trip. It takes 5 hours.
If x = the rate of the boat in still water and y = the rate of the current, write an expression that represents the rate of
the boat going with the current. Type the expression in the space provided.

understand that i don't know the answers

will someone answer his question

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

it has to have an angle of 90 degrees
