Emeline can type at a constant rate of 1/4 pages/minute.
a. what is the ratio of the number of pages to the number of minutes?
b. emeline has to type a 5-page article but only has 18 minutes until she reaches the deadline. does emeline have enough time to type the article? why or why not?
c. emeline has to type a 7-page article. how much time will it take her?

a. 1/4

b. No, she does not have enough time

c. 28 minutes

Step-by-step explanation:

Emeline can type at a constant rate of 1/4 pages/minute.

a.the ratio of the number of pages to the number of minutes = 1/4 that she types 1 page every 4 minutes.

b. For a five page article she will take 5×4 minutes = 20 minutes( as she took 4 minutes for 1 page ). She won,t be able to complete task  before the dead line as she has got only 18 days.

c. Emeline has to type a 7-page article. so, she will take 7×4 minutes = 28 minutes to complete the task.

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
