To divide fractions, you can use Keep, change, flip:
Keep the 3/4, change the division sign to multiplication, and flip the 1/4 to 4/1
3/4 x 4/1
=12/4
=3
Plug in -5 for n
-5^3 + 3(-5)^2
-125 + 3(25) = -125 + 75 = -50
f(-5) = -50
Write 6% as a decimal : 6% = 0.06
Multiply the price of the shirts by 0.06:
Tax = 24.00 x 0.06 = $1.44
