Answer key and explanations
-
D. \(45\)
\(30\%\) of \(150\) is \(0.30\times150=45\).
-
C. \(15\)
\(75\%\) of \(20\) is \(0.75 \times 20 = 15\) games.
-
D. \(25\%\)
\(\frac{20}{80} = \frac{1}{4} = 0.25 = 25\%\).
-
D. \($32\)
The discount is \(40\%\) of \($80\): \(0.40 \times 80 = 32\) dollars.
-
C. \(80\)
If \(12 = 0.15 \times n\), then \(n = \frac{12}{0.15} = 80\).
-
C. \(60\%\)
The shaded region is \(\frac{60}{100} = 60\%\) of the grid.
-
C. \(34\)
\(85\%\) of \(40\) is \(0.85 \times 40 = 34\) questions.
-
D. \(10\)
\(5\%\) of \(200\) is \(0.05 \times 200 = 10\).
