To find the sales tax rate, we can use the formula:

Sales tax rate = (Sales tax / Cost before tax) * 100%

Plugging in the given values:

Sales tax rate = ($25.90 / $370) * 100%
Sales tax rate = 0.07 * 100%
Sales tax rate = 7%

Therefore, the sales tax rate is 7%.

To find out how many miles Abdul drove the truck, we first need to subtract the base fee from the total amount he paid:

Total amount paid - Base fee = Additional charge for miles driven

$146.67 - $14.95 = Additional charge for miles driven

$131.72 = Additional charge for miles driven

We then need to divide the additional charge for miles driven by the rate per mile to find the number of miles:

Additional charge for miles driven / Rate per mile = Number of miles driven

$131.72 / $0.74 = Number of miles driven

178 miles = Number of miles driven

Therefore, Abdul drove the truck for 178 miles.

To find the total number of registered doctors, we can use the formula:

Total number of registered doctors = (Number of female doctors / Percentage of female doctors)

Plugging in the given values:

Total number of registered doctors = 45,700 / 0.173

Total number of registered doctors ≈ 263,959

Rounding to the nearest whole number, the total number of registered doctors is approximately 263,959.
