Answer:
She made 17.5 in commission, and the jewelry store made 332.5.
Explanation:
To find percentages you divide the percentage by 100 ,in this case 5 divided by 100, which results in 0.05. Then you just multiply by the number you are trying to get the percentage from, which is 350. 0.05 x 350 is 17.5 and thats how much hiedi earns in commission. To find how much the jewelry store made you just subtract 17.5 from 350 :)
