See attachment for complete question

Required

Determine the domain and the range

From the complete question, we understand that the study was carried out for 6 days. This represents the domain;

So, we have:

Domain : 0\le x \le 6 i.e. from day 0 to day 6

Also, he experimented with 72ml, and he used an equal amount each day before he used up all the 72mL. This represents the range

Travis has hired Charlie and Dora to plant flowers. Dora can plant 150 flowers in the same time it takes Charlie to plant 120 fl
slega [8]

Answer:

  72

Step-by-step explanation:

If the rates d and c are flowers per day, we have ...

  150/d = 120/c

  d -c = 18

__

Multiplying the first equation by cd/30, we have ...

  5c = 4d

Multiplying the second equation by 4 gives ...

  4d -4c = 72

Adding these equations together, we get ...

  5c +4d -4c = 4d +72

Simplifying and subtracting 4d leaves ...

  c = 72

Charlie can plant 72 flowers per day.
