Assume that the other number is y.
we know that the addition of both number is -9
this means that:
x+y=-9
reorder this equation to seperate the y variable:
y=-9-x
You take $22,000.00 + $625.00= 22,625.00 (which is the sales tax)
Take $22,625.00 x .06=$1,357.50
Then take $22,625.00 + $<span>1,357.50 +$40.00 = $24.022.50</span>
Yes if you were to so 290 times 10 on a calculator or 2,900 divided by 10
