Question 98872: Peter received commissions of $150 and $225. How much be receive from a third sale so his total commission will exceed $500? Answer by doukungfoo(195) (Show Source):
You can put this solution on YOUR website! To find the total amount of commissions earn you need to add them all together.
In this problem Peter has already received two commissions which are $150 and $225. The unknown amount is the third commission. Lets set this amount equal to x. Now we can write an equation to find the unknown amount x.
$150 + $225 + x = $501
first add the two known commissions together
$375 + x = $501
now to solve for x subtract $375 from both sides of the equal sign
$375 - $375 + x = $501 - $375
x = $126
So thats it. The third commission must be at least $126 for the total commissions earned to exceed $500
