QuoteOMG! I can't believe you're doing that in your free time! i actually like math and i like doing weird stuff in my free time. some stuff includes drawing, reading scientific books, and playing video games. i also like to help others out when i can. people always thought i was going to grow up to be a math teacher back when i was in high school.

QuoteTorrance split an inheritance between two investments, one paying 7% and the other paying 10%. He invested twice as much at 10% as at 7%. The combined annual income from two investments was $4050. How much did Torrance inherit?i'll help with the first one and then see if you can do the other one on your own... i'll just break it down into steps so you can see how i came up with the answer...(1) understand what you are looking for.(2) assign variables and understand what those variables stand for. we'll use x and y say that x stands for an amount of money and y stands for the amount of money inherited.y=inheritancex=the inheritance that was split up(3) set up equations...the inheritance was split up two ways... one investment was twice as much as the other...y=2x+x --> y=3xTorrance split an inheritance between two investments, one paying 7% and the other paying 10%. He invested twice as much at 10% as at 7%. The combined annual income from two investments was $4050...2(.1x)+.07x=4050(4) solve the equations...2(.1x)+.07x=4050 ... multiply the 2 and the .1 x.2x+.07x=4050 ... add the two x's together.27x=4050 ... divide both sides of the equation by .27x=15000 ... now go back and plug x into the first equationy=3(15000) ... mutiplyy=45000the teacher might want you to write the answer out in a complete sentence or something...Torance inherited $45,000.(5) reread the problem and make sure you answered the question(6) check your answer
