In a recent year, companies spent a total of $84.8 billion on newspaper, television, and radio ads. The total amount spent on television and radio ads was only$2.6 billion more than the amount spent on newspaper ads alone. The amount spent on newspaper ads was $5.1 billion more than what was spent on television ads. How much was spent no each form of advertising? (Hint: Let the variables represent numbers of billions of dollars) Help on this would be greatly appreciated!!!! Todd 2. Let$\displaystyle n,\ t,\ r$be the amount of money spent in Newspapers, Tv and Radio, in billions of dollars. Then we have:$\displaystyle n+t+r=84.8$(amount spent all together)$\displaystyle t+r-n=2.6$(tv and radio 2.6 billions more than newspapers) We subtract the second equation from the first, and the result is$\displaystyle 2n=82.2\Rightarrowx=\frac{82.2}{2}=41.1$. And we know that$\displaystyle t=n-5.1=41.1-5.1=36$We substitue the values of$\displaystyle t$and$\displaystyle n$in the first equation, and we get$\displaystyle 84.4=n+t+r=41.1+36+r\Rightarrow r=84.8-41.1-36=7.7$So the result is$\displaystyle n=41.1,\ t=36,\ r=7.7\$
