Step-by-step.
30255.5=a90.75
Step 1: Cross-multiply.
30255.5=a90.75
(3025)*(90.75)=a*(5.5)
274518.75=5.5a
Step 2: Flip the equation.
5.5a=274518.75
Step 3: Divide both sides by 5.5.
5.5a5.5=274518.755.5
a=49912.5
Five twelfths are left of the candy bar
$193.50
start by multiplying 240 by .25 (25%) to find out how much is 25% of 240. this equals 60.
then, subtract $60 from $240. equals 180.
next, to add the sales tax, multiply 180 by 0.075 (7.5%) this is $13.50.
lastly, add the tax, which is $13.50, to the suit's sale price, which is $180.
180+13.5= $193.50
Well $9.75 times 25 hours is $243.75.
Then you take that and multiply it by 10.
So she earned $2,437.5
