$480 a month. At 9 dollars an hour I would make $48 dollars a day pre tax, roughly $6 bucks an hour. at $15 I would make 96 a day pre tax. which is roughly $12 per hour. Any help on what rate I should mention would help...
If you get twice interest during a year , then it is per annum compounding interest. In per annum interest rate you will get specific rate of interest in a year for your investment. You have fixed deposit of $10,000 and you will get 15%interest per annum for 10 years. This how per annum interst works.
Every month an interest of 2% per month for an amount of $1000 works out as follows. At the end of the first month the the amount along with interest is 1000+1000*2% = 1000(1.02) = 1020 which is $1000+ interest $20. At the end of the 2nd month he has to pay 1020(1.02) = 1000(1.02)^2 = $1040*4 .= $1000 + interest $ 40.4.
