Question

Rich works in a home lighting store. He is paid $250 per week and 3% on all sales over $1000. During one year, his average weekly sales were $8800. About how much did he earn during the year?

Answer 1

pae=250$/week +3% av (sell-1000$)

averaej sell=8800$/week

3% av 8800$=0.03*8800=264$/week

averaej pae=250$+264$=514$/week

(52 weeks) * 514$/week=26,728$
