A DVD movie sells for $25 and the sales tax is 6.5%. What is the total cost of the movie to the nearest penny
MA_775_DIABLO [31]
Hello! First, let's add 1 to the tax rate in decimal form. 6.5% is 0.065. 1 + 0.065 is 1.065. Multiply that number by 25 to get 26.625 or 26.63 when rounded to the nearest penny. The total cost of the movie is $26.63.

Note: If a question asks for the total cost with tax, always add 1 to the tax rate in decimal form. That way, you will get straight to the answer and not have to do any complicating work.

Quantity of paint left = \frac{389}{480} gallons

Solution:

Quantity of yellow paint = 1\frac{1}{5}=\frac{6}{5} gallons

Quantity of green paint = 1\frac{1}{6}=\frac{7}{6} gallons

Quantity of blue paint = \frac{7}{8} gallons

Quantity of paint used = \frac{3}{4} gallons of each paint

Quantity of paint left = 1-\frac{3}{4}=\frac{1}{4} gallons of each paint

Quantity of paint left = (\frac{6}{5}+\frac{7}{6}+\frac{7}{8})\times\frac{1}{4}

Taking LCM for 5, 6, 8, we get LCM = 120

(\frac{6}{5}+\frac{7}{6}+\frac{7}{8})\times\frac{1}{4}=(\frac{144}{120}+\frac{140}{120}+\frac{105}{120})\times\frac{1}{4}

                         =(\frac{389}{120})\times\frac{1}{4}

                         =\frac{389}{480}

Hence, Mark will have \frac{389}{480} gallons of paint left after painting the mural.
