Perfume has a 1;5 ratio of fragrance oil to its total volume, 3mL of fragrance oil, what is the total volume of her perfume?

18ml

Step-by-step explanation:

since the ratio is 1:5 of fragrance oil to perfume and the volume of the fragrance oil is 3ml

we can make the ratio becomes 1 x 3 : 5 x 3

thus making it 3 ml and 15 ml,.adding these makes the whole perfume which has the volume of 18ml

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

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
