Suppose x is the rate at which the boat travels at still water.
let y be rate in moving water
up stream is x-y 
down stream is x+y
the 1/3(x-y)=5
1/5(x+y)=5
solve the system
x-y=15
x+y=25
add the equation to cancel y
we get 2x=40
x=20 
therefore the boat is moving at rate of 20 miles for hour in still water

Mekhanik [1.2K]

The sales tax percentage of the store manager report is 7.41%

<h3>How to solve for the sales tax percentage</h3>

Customers are subject to a charge known as sales tax when they buy goods and services.

It is a pass-through tax, which means you must collect it from clients and send the money to your state or local government. the seller do not contribute sales tax.

The sales tax is first calculated by

= price after tax - price before tax

= 513 - 475

= 38

sales tax percentage is calculated using the formula

= (Tax amount / Price before tax) × 100%

= (38 / 513) * 100

= 7.4074

= 7.41%
