A student uses a solution that contains 16 grams of water to conduct an evaporation experiment.

• At the end of one hour, the amount of water in the solution has decreased by 3.5%.

• At the end of two hours, the amount of water in the solution has decreased by another 4.25%

Which calculations can be used to determine the amount of water, in grams, remaining in the solution at the end of the second hour?

• Step 1: 0.035 x 16 = 0.56

  Step 2: 16 – 0.56 = 15.44

  Step 3: 0.0425 x 15.44 = 0.6562

  Step 4: 16 – 0.6562 = 15.3438

• Step 1: 0.035 x 16 = 0.56

  Step 2: 16 – 0.56 = 15.44

  Step 3: 0.0425 x 15.44 = 0.6562

  Step 4: 15.44 – 0.6562 = 14.7838

• Step 1: 0.35 x 16 = 5.6

  Step 2: 16 – 5.6 = 10.4

  Step 3: 0.425 x 10.4 = 4.42

  Step 4: 16 – 4.42 = 11.58

• Step 1: 0.35 x 16 = 5.6

  Step 2: 16 – 5.6 = 10.4

  Step 3: 0.425 x 10.4 = 4.42

  Step 4: 10.4 – 4.42 = 5.98
