Written out numerically, it is 4x4x4. To work this out you multiply 4x4= 16 and then you have one more 4 to multiply by, so you multiply 16x4=64
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.
