Number of experimental pinks drawn / number of experimental picks...
4/(4+24+22)
4/50
2/25 or (8%)
The equation would be Y=15x+150 because 10% of 150 is 15. Next you coun up how many months you have up untill August and replace the x with it. So the equation would be Y=15(7)+150. ___Y=105+150___Y=$255. So $255 would be your answer.
I don't really understand this question do u have a pic?
