Step-by-step explanation:
0 years = 96 grams
After 3 years , the amount left is 1/2 of what you started with
3 years = 1/2 *96 = 48 grams

Answer:
3.6 hours
Step-by-step explanation:
step 1
we know that
Pipe A fills a tank in 9 hours
so
The 100% of the tank is filled in 9 hours
using proportion
Find out what percentage of the tank is filled in 1 hour
step 2
we know that
Pipe B fills a tank in 6 hours
so
The 100% of the tank is filled in 6 hours
using proportion
Find out what percentage of the tank is filled in 1 hour
step 3
we know that
In one hour the percentage of the tank fill with both pipes is equal to
using proportion
