An auctioneer sold items totaling $42,000. if her rate of commission was 7%, what was her income from commissions?

So another way of doing this is:

10% of $42,000 is $4,200
So
5% is $2,100

Now

1% is $420 x 2 which means 2% is $840

So simply do:

$2,100+$840 = $2940

So the 7% income is $2940

Just made it more simple for you hope it helps.

Ican’t sorry i would if i could
