Tyler’s brother works in a shoe store. Tyler’s brother earns a commission. He makes 2.5% of the amount he sells. Last week, he sold $900 worth of shoes. How much was his commission?

Step-by-step explanation:

A) To figure this out, convert 2.5% into a decimal, which is 0.025. Then, multiply the amount he sold by his commission percent. So $9000 * 0.025 =$225

B) The formula for percent change (or in this case percent markup) is (new value - old value)/old value *100%. So, (80-50)/50*100% = 30/50*100%=60%.

C) First, calculate the amount his hourly rate will increase by. So, multiply 12 by 5%, which is $12*0.05=$0.60. Then, add this amount to his current hourly rate. So he now makes $12.60.

you would have to sell 24 bracelets.
