The sales tax for an item was $25.90 and it cost $370 before tax.

Find the sales tax rate. Write your answer as a percentage.

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%.

Abdul rented a truck for one day. There was a base fee of $14.95, and there was an additional charge of 74 cents for each mile driven. Abdul had to pay $146.67 when he returned the truck. For how many miles did he drive the truck?

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.

In a recent year, 17.3% of all registered doctors were female. If there were 45,700 female registered doctors that year, what was the total number of registered doctors?

Round your answer to the nearest whole number.

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.
