DIA [1.3K]

Answer:

The answer to your question is: 3.7 hours

Step-by-step explanation:

Kam can make 72 cookies/ 3 hours

Madison can make 120 cookies/4 hours

Time to make 200 cookies together = ?

First, calculate the number of cookies make per hour

Kam 72 ---------------- 3

x ---------------- 1 hour

x = 72/3 = 24 cookies/h

Madison

120 ------------- 4 hours

x --------------- 1 hour

x = 120 / 4 = 30 cookies

Now we write and equation where "t" will be time

24t + 30t = 200 and solve it

54t = 200

t = 200/54

t = 3.7 hours
