Answer
Find out the how much did kerry pay in tax .
To proof
As given
Kerry bought a bag of dog food for $37.99.
If sales tax is 7.6%
7.6 % is written in the decimal form
[tex]= \frac{7.6}{100}[/tex]
= 0.076
7.6 % of the $37.99 = 0.076 ×37.99
= 2.88724
= $2.89 ( approx)
Kerry pay in the sales tax be $2.89
Hence proved
Total cost of a bag of dog food = $37.99.
Let us assume cost of a bag of dog food excluding sales tax = $x.
Sales tax is 7.6 %.
Total cost of a bag of dog food including tax = x+ 7.6% of x.
x + 0.076x = 37.99
1.076x = 37.99.
Dividing both sides by 1.076, we get
1.076x/1.076 = 37.99/1.076.
x = 35.31.
Therefore, cost of a bag of dog food excluding sales tax = $35.31.
Sales tax = 7.6 % of $35.31 = 0.076 × 35.31 = 2.68.
