Answer:
He must make $7,500 in sale
Step-by-step explanation:
Let's say:
s = amount make in sales per week
P1 = weekly salary of Plan 1
P2 = weekly salary of Plan 2
P1 and P2 can be expressed using the fixed amount plus the commission.
P1 = 600 + 0.02s
P2 = 0 + 0.1s
P2 = 0.1s
If both plans result in the same salary:
P1 = P2
600 + 0.02s = 0.1s
0.1s - 0.02s = 600
0.08s = 600
s = 600/0.08
s = $7,500
