Answer:
There were 120 yellow water bottles in the shipment

Answer:
13.18651685
13.9
Explain:
890-238=652
652/890=0.7325842697 (Find out the percentage)
We know that 1 gram of Element X will be fully decayed in 18 minutes and half of it in 9 minutes.
0.7325842697x18=13.18651685
As you see 18/13.18651685 will equal to 18 (not exactly since it is rounded)
And of course we need to round it to nearest tenth. So the answer would be 13.9!
