Video Transcription

Problem number 7. Denise fired a silver rocket and a gold rocket at the same time.  The rocket exploded to 20 stars in total. The gold rocket exploded into 6 more stars than the silver one.  How many stars did the gold rocket explode into? A-9, B-10, C-12, D-13, or E-15? If we take a look, we have the gold rocket that exploded into 6 more stars than the silver rocket.  So this part right here is 6, and the extra stars that the gold rocket exploded into. Now 20 minus 6 is 14, and say these two are the same now, those  would both explode into 7 stars, which is 14 total. And then if we look at this, 7 plus 6 is 13. So the gold rocket exploded into 13 stars, so our answer is D.
