If total advertising expenditures on television advertising declined 4.1% to $141.7 billion in the current year, how much was sp

Vanyuwa [196]

Using proportions, it is found that $147.8 billion was spent on television advertising in the previous year.

$x, in billions, was spent on advertising expenditures on television last year.

This year, the amount declined 4.1%, hence it is 100% - 4.1% = 95.9% of last year's amount, that is, 0.959x.

This year spending's is of 141.7 billion, hence, the equation is:

$0.959x = 141.7$

$x = \frac{141.7}{0.959}$

$x = 147.8$

$147.8 billion was spent on television advertising in the previous year.
