Last year, trey had $10,000 to invest. he invested some of it in an account that paid 7% simple interest per year and he invested the rest in an account that paid 5% simple interest per year. after one year, he received a total of $620 in interest. how much did he invest in each account?

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
