That is one of my 10 assignments. It would be much appreciated if you did all the work like it is telling me to do so I can understand it for the rest of the questions.
Thanks so much! Found 2 solutions by nerdybill, gonzo:Answer by nerdybill(7384) (Show Source):
You can put this solution on YOUR website! Francine is earning $7.00 per hour. She gets a 20% raise in pay. By what fraction should you multiply to find how much more per hour she will now make? What will Francine's new hourly rate be?
~~READ~~ the problem and break it into parts to solve it. Identify any irrelevant information in the problem.
No irrelevant information.
~~SHOW/WRITE
% is "per one hundred"
therefore
20% in fractional form is 20/100
.
So, if Francine got a 20% raise it would be:
7 * 20/100
= 7 * .20
= $1.40 (raise)
.
~~WRITE~~ your answer.
New hourly rate then is:
7 + 1.40 = $8.40 per hour

-----
she makes $7.00 an hour.
she gets a 20% raise.
20% translates to a rate of .2 as shown below in the next section.
her new hourly rate would be the existing rate plus the raise which becomes $7.00 + (.2 * $7.00) = $7.00 + 1.40 = $8.40 per hour.
-----
you need to remember that the rate is the percent / 100.
if you want to get a percent of something, you need to divide the percent by 100 to get the rate and then multiply that something by the rate.
-----
20% of something is .2 times that something.
20% is called the percent.
20%/100% is called the rate.
20%/100% = .2 in this case.

the problem was straight forwards. there was no irrelevant information.
-----
~~SHOW~~ each step of your math work.
-----
i did that above.
i showed how to get the raise and then add it to the base salary to get the new salary.
-----
~~WRITE~~ an explanation describing what you did and why you solved the problem the way you did.
-----
i needed to find out what the raise was and add it to the base salary to get the new salary as shown in the step by step details.
~~WRITE~~ your answer.
done above.
-----
it's nothing more complicated than figuring out how to solve the problem and then describing the steps you will take and then working the problem to get the solution.
if you explain as you go then the explanation is embedded in the details of solving the problem.
