Answer:
30%
Step-by-step explanation:
Here we want to setup the equation
[tex]y = a - (a\times x)[/tex]
where y is the discounted price, a is the normal price and x is the percent off. so now we wanna plug in known values and solve for percent off.
[tex]45.49 = 64.99 - (64.99x)[/tex]
through algebra,
[tex] - 19.5 = - (64.99x)[/tex]
[tex] \frac{ - 19.5}{ - 64.99} = x[/tex]
[tex]x = .3000...[/tex]
so in percentage that is 30%
