I need a formula found for my situation and i believe it is algebra related

hat the actual tax paid. (See example: http://www.csgnetwork.com/salestaxpercentcalc.html ) If I know my subtotal is: $27.99 And my Tax Amount is:: $1.96 How can I know that the Tax RATE is: 7.00 ?

hat the actual tax paid

ing to figure this out I need help

s with formula Complete the square Solve linear simultaneous equations Solve quadratic simultaneous equations

join together? I just need to understand how to write a molecular equation.

fferent values and have a universal formula for something such as: I purchase $300 of currency A - @ 0.00543 per dollar Currency A goes up in price to 0.00600 per dollar How much profit do I make?

formula online to help.. It should be a simple straightforward problem but i just can not for the life of me figure it out. are you able to provide me with a formula or point me in the right direction? The problem is: Solution A has a 50% concentration Solution B has a 100% concentration Solution C has a 5% concentration you have 5L of each solution to utilize as well as unlimited quantities of water to dilute solution concentrations if needed. Part A Make a final solution of 100ml with solution concentrations of Solution A 15%, solution C 5% and solution C 80%. how much of each solution will you need to make your final 100ml solution? Part B using the above solutions how many 100ml final solutions can you produce with the 5L volumes? No matter how I work it i can't make the solution to the correct concentrations. Thank you for your help. John

sted and I can see any changes in realtime. What I need is to take the duration in cells A2:A1000 and factor the dollar value in corresponding cells B2:B1000 in a way that causes the average amount earned per hour to calculate in cell D2. I'd appreciate a bit of help here, and I;d prefer if you could just plug the formula directly into cell D2 using the link below. The link to the editable document is: https://docs.google.com/spreadsheets/d/1lEJIPiSZJk9LYUTSA4oeDwyLXCVd18Zdewm6gnjxcXo/edit?usp=sharing Thanks!
