Question 763585: Please help me solve this word problem
Bev was offered plan A: a flat salary of $2750 semi monthly of plan B: $2100 semi monthly plus as 7 1/4% commission of her sales. If Bev were confident that she could regularly bring in $9000 per month in sales. How much more can she expect to make with the better plan?

You can put this solution on YOUR website!
Let +S+ = her monthly salary + any commission
Let +a+ = her amount of sales in plan B
With plan A:
+S+=+2%2A2750+
+S+=+5500+
With Plan B:
+S+=+2%2A2100+%2B+.0725a+
+S+=+2%2A2100+%2B+.0725a+
+S+=+4200+%2B+.0725%2A9000+
+S+=+4200+%2B+652.5+
+S+=+4852.5+
+5500+-+4852.5+=+647.5+
She can expect to make $647.50 more per month with plan A
