A stereo salesperson earns a salary of $1900 per month, plus a commission of 4% of sales. The salesperson wants to maintain a monthly income of at least $2200. How much must the salesperson sell each month? PLEASE HELP!!! I WILL GIVE 25 POINTS!!!!!
percent means parts out of 100 4%=4/100=0.4/10=0.04/1=0.04 4% of sale=0.04 times sales so we have at least means > so earnings>2200 earnings=1900+comission on sales commision on sales=0.04 times sales 2200<1900+0.04timessales solve for sales
2200<1900+0.04 times sales subtract 1900 from both sides 300<0.04 times sales divide both sides by 0.04 7500<sales
