Nick is now seven times as old as harry. in 6 years , nick will be five times as old as harry. how old will harry be in 6 years?

18 years

Step-by-step explanation:

Let Nick age is x years and Harry's age is y years.

Hence, we have the equation

x = 7y  ......(1)

After six years, Nick's age is (x+6) and Harry's age is (y+6)

Hence, we have

Plugging x = 7y, we get

Hence, from equation (1)

x = 7(12)

x =84

In 6 years, Harry will be of 12 + 6 =18 years.

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
