Astudent uses a solution that contains 16 grams of water to conduct and 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?

c
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: 0.35 x 16 = 5.6
step 2: 16 -5.6 - 10.4
step 3: 0.425 * 10.4 = 4.42
step 4: 16-4.42 11.58
d.
b. 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: 10.4 -4.42 = 5.98
what is the answer
