Answer:
51 + 85 = 136
Step-by-step explanation:
Hi,
The ratio of two numbers is 3 to 5.
Let x represent the constant of the proportionality
3x + 5x = 136
8x = 136 (divide both sides by 8)
x = 17
The numbers are:
3*17 = 51 and
5*17 = 85

Cost of TV = $1000
Sales Tax = 8% x $1000
Sales Tax= 0.08 x $1000 | Rewrite 8% as decimal
Sales Tax = $80
Price after tax = $1000 + $80 | Add cost of TV and tax
Price after tax = $1080
