Everyday day you make $30 -plus- 2/9th of your sales. 1)To convert a fraction into a percentage decimal you divide the numerator by the denominator:2 divided by 9= .22 = 22%in turn, you earn $30 plus 22% of your sales. to figure out what dollar amount OF SALES (only)go you need to earn $100. you have to subtract 22% out of $100 and also subtract the $30you automatically make because it only asks for the dollar amount of sales. therefore: -to get 22% out of a 100 you multiply: 100*.22= 22100-22=7878-30=48.total dollar amount of sales needed to earn $100 is: $48.
