Jane works at a store where she earns a base salary of $187.70 per week plus a commission of 20% of sales. if jane sold $810.30 worth of merchandise last week, what was her total pay?

810.30/x=20/100

cross multiply

20x=81,030

divide both side by 20

20x/20=81,030/20

x=$4051.50 this is just for commission.

so...

Total pay= $4051.50+187.70

Total pay= $4239.20
