So, Katherine can do 0.1 of the job per hour. (if she needs 10 hours for the job, each hour she can do the whole divided by the time, so 1/10, which is 0.1)
if in two hours she and Marina can be done, then Marina will do 1(the whole job)-2/10 (twice as much as she can do in an hour)=0.8 of the job. So if Marina does 0.8 of the job in two hours, each hour she will do half of it: 0.4 - and this is the correct answer

Answer: Sandra's salary in the previous year was $48,000
Step-by-step explanation:
Hi, the expression given is missing the $2000 more that she earns this year.
0.14 (x +2000) =7000
Where:
- <em>x is Sandra's salary in the previous year.
</em>
- <em>0.14 is the decimal form of 14% (14/100=0.14)
</em>
Solving for x :
0.14(x) +0.14 (2000) =7000
0.14x +280 =7000
0.14 x = 7000-280
0.14x = 6720
x = 6720/0.14
x=48,000
Sandra's salary in the previous year was $48,000
