You need $315 worth of sales, if I'm right. $100-30 is $70. 70/x=2/9. 70x9=630/2=315.
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= 22
100-22=78
78-30=48.
total dollar amount of sales needed to earn $100 is: $48.
