Simplify \( 5 \log _ { 2 } k - 8 \log _ { 2 } m + 10 \log _ { 2 } n \) 

\( 7 \log _ { 2 } ( k - m + n ) \) 

\( \log _ { 2 } \frac { k n } { m } \) 

\( \log _ { 2 } \frac { 50 k n } { 8 m } \) 

\( \log _ { 2 } \frac { k ^ { 5 } n ^ { 10 } } { m ^ { 8 } } \) 

The demand equation for a certain product is given by \( p = 106 - 0.08 x \) , where \( p \) is the unit price (in dollars) of the product and \( x \) is the number of units produced. The total revenue obtained by producing and selling \( x \) units is given by \( R = x p \) . 

Determine prices \( p \) that would yield a revenue of \( 8140 \) dollars. 

Lowest such price \( = \) ______ dollars

Highest such price \( = 99.48 \) dollars

Sean began jogging to live a healthier lifestyle. On his first run, he ran one-half mile. He increased his workouts by adding two miles a month to his run. He wrote the equation \(f ( x ) = 0.5 + 2 x\) to model his progress. The variable \(x\) represents the number of 

miles he runs. 

months he runs. 

miles he ran the first day.

Stella and Harper determine that 25 less than the product of their ages, in years, is 183. Stella's age is 3 more tha Harper's age, x. 

Select all the equations that could be used to find the ages of Stella and Harper. 

x(x + 3) = 158

x(x + 3) = 208

25 - x(x+3) = 183

x(x + 3) - 25 = 183

x + (x+3) - 25 = 183
