Question

Sales tax on a $400 stereo is $16. What is the tax on a $650 tv?​

Answer 1

the answer is 26 no decimal i got it right on my test.

X=tax on a $650 TV

16/400 = X/650

16*650=400*X

10,400=400*X

10,400/400=X

26=X

Answer 2

$2.6

Explanation:

firstly we find percentage of tax .

(16/400) * 100

= 16/4

= 4 %

now ,

so 4% of 650

= (4*650)/ 100

=260/100

= $2.6
