The total amount paid for vase is $ 41
<em><u>Solution:</u></em>
Given that
Cost of vase = $ 34.99
Shipping charge = 3 dollars
Sales tax = 8.25 % was paid on the subtotal which included the shipping charge
To find: total amount paid for vase
total amount paid for vase = Cost of vase + Shipping charge + sales tax
Let us first find the sales tax
Given that 8.25 % was paid on the subtotal which included the shipping charge
Subtotal = 34.99 + 3 = 37.99
So 8.25 % of 37.99 was paid as sales tax
Therefore sales tax amount paid = $ 3.1341
total amount paid for vase = Cost of vase + Shipping charge + sales tax
total amount paid for vase = 34.99 + 3 + 3.1341 = 41.1241 ≈ 41
Therefore total amount paid for vase is $ 41
Answer:
No positive value of n
Step-by-step explanation:
we have to find out for how many positive values of n are both
our-digit integers
Let us consider first cube
we get 4digit lowest number is 1000 and it has cube root as 10.
Thus 10 is the least integer which satisfies four digits for cube.
The highest integer is 9999 and it has cube root as 21.54
or 21 the highest integer.
Considering 3^n we get,
3^10 is having 5 digits and also 3^21
Thus there is no positive value of n which satisfy that both n cube and 3 power n are four digits.
