Maxwell makes a 3% commission on the mobile phones he sells .if he earns $500 per week before commission ,how much merchandise will he have to sell to make a total of $1075 this week ? me plzzz show how u solved it .

I could be really wrong in this question but for this one u have to subtract the wanted total for the week $1075 subtracted by what he earns in a week $500
1075-500=$575
so a commission is basically the percentage you make for yourself from whatever you sold, so if Maxwell wants $575 extra and he can only get that by getting 3% of whatever the amount of what he sells so you can make an equation as such,  
now if you divide .03 from both sides then you get an equation to find x which is the amount he has to sell in order to make $575.
so after you divide 575/.03 you are supposed to get this number $19166.67 rounder to the nearest hundredth. 
so the answer is that he has to sell $19166.67 worth of merchandise in order to achieve that $1075 a week.

Hopefully that helped you out and is the right answer!!! 

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
