Best ResponseYou've already chosen the best response.00.08x + 0.095(20000x) = 1675 0.08x + 1900 + 0.095x = 1675 0.175x + 1900 = 1675 0.175x = 375 2142?

Best ResponseYou've already chosen the best response.2\[.08x+.095(20000x)=1675\] \[.08x+1900.095x=1675\] \[.015x+1900=1675\] \[.015x=225\] \[\frac{.015x}{.015}=\frac{225}{.015}\] \[x=15000\]
