Answer:
- $5.60 sales tax
- $75.60 total cost
Step-by-step explanation:
You have correctly found the sales tax to be ...
$70.00 × 0.08 = $5.60 . . . sales tax

Answer: The correct option is
(D) 60.
Step-by-step explanation: Given that the number of stamps that Kaye and Alberto had were in the ration of 5:3 respectively.
After Kaye gave Alberto 10 of her stamps, the ration of the number of Kaye had to the number of Alberto had was 7:5.
We are to find the number of stamps that Kaye had more than Alberto.
Let the number of stamps Kaye and Alberto has are 5x and 3x respectively.
Then, according to the given information, we have

So, the number of stamps that Kaye had = 5 × 30 = 150
and
the number of stamps that Alberto had = 3 × 30 = 90.
Therefore, the number of stamps that Kaye had more than Alberto is

Thus, Kaye had 60 stamps more than Alberto.
Option (D) is CORRECT.
