What is an expression for the spending money you have left after depositing 2/5 of your wages and savings evaluate the expression for weekly wages of $40 50 dollars $75 and $100

OpenStudy (iwillrektyou):

Hi, do you know how to find percentages of numbers?

OpenStudy (iwillrektyou):

Okay, so if you were to find 25% of 200, you do 200 * 0.25 = 50

OpenStudy (anonymous):

Ok

OpenStudy (iwillrektyou):

For this, you do the same thing. Do you want me to show you the first one?

OpenStudy (anonymous):

Yes plzz

OpenStudy (iwillrektyou):

Ok, 2/5 is also 40%, written in decimal form as 0.4 0.4 * 40 = 16

OpenStudy (anonymous):

So 0.4 * 75 would be 30

OpenStudy (iwillrektyou):

Yes. Great job! Now just one more. Doing it with 100 is very easy, because a percent is out of 100.

OpenStudy (anonymous):

So it would be 40

OpenStudy (iwillrektyou):

Yes. Great job! Those are the answers.

Thx Yhuu really helped me out

OpenStudy (iwillrektyou):

No problem! You can tag me in future problems if you have them.

OpenStudy (anonymous):

Ok

OpenStudy (anonymous):

Can Yhuu help with simplifying

OpenStudy (iwillrektyou):

Sure, I will try.

OpenStudy (anonymous):

Ok simplify the expression ( 20-14) cubed divided by 12

OpenStudy (anonymous):

Nvm I got thx though bt I have another queation instead will Yhuu help?

OpenStudy (iwillrektyou):

Ok. So, based on order of operations, you first solve the parenthesis: (20 - 14)^3 divided by 12 --> (6)^3 divided by 12

OpenStudy (anonymous):

Suppose you make $12 an hour as a lifeguard at the community pool during the summer let H represent the number of hours you work in a week write an expression that represents the amount of money you earn in a week and evaluated for h equals 15

OpenStudy (iwillrektyou):

Hmm... I think you are supposed to find the number of hours in a week in order to solve. The original equation is: 12h. You just have to substitute 15 for h and solve.

OpenStudy (anonymous):

Ok thx got it

OpenStudy (iwillrektyou):

Np! I will try to attend to any other stuff you tag me to, and I will try to help you as much as possible. Hopefully I'm not in school or extracurricular activities when that happens. :)

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (iwillrektyou):

OpenStudy (anonymous):
