Answer:
36 dream catcherss
Step-by-step explanation:
Jane's production rate:
1 dream catcher
6 days
Zena's production rate:
1 dream catcher
4 days
Production rate when working together:
1
6
+
1
4
=
5
12
. This ratio means it will take 12 days to make 5 dream catchers.
Set up a ratio for 15 dream catchers.

d
→ 5d = (12)(15) → 5d = 180 → d = 36
Answer: 36 days
Step-by-step explanation:
Hi, to answer this we have to calculate the production rate of each one, by dividing the number of catchers by the time spent.
Jane: 1/6 dream catcher per day
Zena: 1/4 dream Catcher per day
Adding both results:
1/6 +1/4 =5/12 dream catcher per day (both)
Finally we have to divide the 15 dream catchers needed by the rate (5/12 per day) to obtain the number of days that will take to make 15 dream catchers
x = 15 / (5/12) =36 days.
