Question

It’s due tomorrow I really need help

Answer 1

B.

Explanation:

As the steps imply,

• Step 1 is to first convert the 3.5% (0.035) and then multiply it by 16 to find out by how many grams the amount should decrease (0.035 * 16 = 0.56).
• Step 2 is to subtract this amount from 16 to find the amount remaining after one hour (16 - 0.56 = 15.44).
• Step 3 is to convert 4.25% to a decimal (0.0425) and multiply it by the amount remaining at the end of one hour to find out by how many grams this amount should decrease after two hours (0.0425 * 15.44 = 0.6562)
• Step 4 finally is to subtract this amount from 15.44 to find the amount remaining after two hours (15.44 - 0.6562 = 14.7838)
