3times 45 plus 920 minus 23 time 75 plus 82 plz tell me the thnx!

3x45+920-23x75+82

If you want to do it by using the PEMDAS method (parenthesis, exponent, multiplication/division, addition/subtraction), then the answer goes like this:
135+920-1725+82
1055-1725+82
-670+82
-588

But if you have to do it in the order that it is written in, then the answer is found like this:
135+920-23x75+82
1055-23x75+82
1032x75+82
77400+82
77482

Hope this helps :-)

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
