alfredo bought a fishing pole for 60 off it's original price of $97 if the tax was 4% how much did alfredo pay for the fishing p
Agata [3.3K]

Answer:

$40.4

Step-by-step explanation:

The regular price of the fishing rod is $97

There is a 60% discount from that price.

The discount is equal to 60% of $97 which is equal to .60 * $97 which is equal to $58.2

Discount is like a markdown, so subtract $58.2 from the price of the item before the change to get $97 - $58.2 = $38.8 

This is the price of the item before tax is applied.

Now you apply the sales tax of 4%.

4% of $38.8 is equal to .04 * $38.8 which is equal to $1.552

Tax is like a markup, so add $1.552 to the price of the item before tax was applied to get a selling price of $38.8 + $1.552 which is equal to $40.352

Round it up and the answer is $40.4

Simon drove for 2 1/2 hours to get from his house to the beach. Simon averaged 55 miles per hour on the trip. What is the distan
Sav [38]

Answer:

The distance from Simon's house to the beach is 137.5 miles

Step-by-step explanation:

we know that

The speed is equal to the ratio of the distance and the time

Let

s ----> the speed in mph

x ----> the distance in miles

y ---> the time in hours

s=\frac{x}{y}

we have

s=55\ mi/h

y=2\frac{1}{2}\ h=\frac{2*2+1}{2}=\frac{5}{2}\ h

substitute in the formula and solve for x

55=\frac{x}{(5/2)}

x=(5/2)55\\x=137.5\ mi
