#6) He gets 1.5 percent commission on total contracts and then an additional 2.5 percent on anything over 1.5 million.
Since his total contracts is 2,555,500,
He gets 1.5 percent of that, plus 2.5 percent of "2,555,500 - 1,500,000" which is 1,055,500
So his total pay is:
0.015*2,555,500 + 0.025*1,055,500 = $64,720
#7) Tobias earns $1,959 per month plus 6.3% commission on sales. So let "s" be sales. His monthly earnings can be calculated by:
1,959 + 0.063s
In order for this amount to be $2,784.84, we need to solve:
1,959 + 0.063s = 2,784.84
Solve:
0.063s = 825.84
s = $13,108.57143
or $13,108.57
