180 times 4/100= 7.20- Sales tax
180+7.20= $187.20 is the total cost

You just have to go 7x28=[7x20]+[7x8]=196
Let:
Vbu= Volume of the buret
Vbk= Volume of the beaker
A buret initially contains 70.00 millimeters of a solution and a beaker initially contains 20.00 ml of the solution the buret drips solution into the Beaker. each drip contains 0.05 mL of solution, therefore:
x = Number of drips
a = volume of each drip

after how many drips will the volume of the solution in the buret and beaker be equal ? Vbu = Vbk:
Volume=1/3π<span>×</span>r²×h^(Applies for any "right cone")^
Therefore your answer would be
A.1206 cm³
