Answer:
All the none-zero digits given should be included when written in scientific notation. But also any trailing zeros written after non-zero digits should also be included.
For example in 0.00900 the 900 is significant because the person who included the trailing zeros is saying look I measured this far and these zeros are significant.
90b + 150g > 500
0.35b + 2.50g < 15.00
