Please help, if you can use explanations would be much better Consuela is a photographer and must mix a chemical in the ratio of chemical:water = 1:9. If she uses 15 fl oz of water in the mixture, how many fl oz of the chemical should she use

x= 15/9 fl oz

Step-by-step explanation:

 write the such that chemicals are on one side of : and water on the other

   chemical : water

                 1 : 9

x chemical : 15 of water

now we know that

x/1 = 15/9  cross multiply to find x

x= 1*15/9 = 15/9  ≈ 1.67 fl oz

i agree because i see the other persons thinking is clear

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
