Ashopper bought shoes marked $40. the sales tax rate is 5%. how much is the total including sales tax?

First we must see how much is 5% of $40. To do this you must create at proportion:

5 is a percent and percent's are always taken out of the 100. This means that one proportion will have 5 as the part and 100 as the whole

We want to know what 5% of 40 is. This means 40 is the whole and the unknown (let's make this x) is the part.

Here is your proportion:

Now you must cross multiply

x*100 = 40*5

100x = 200

To isolate x divide 100 to both sides

100x/100 = 200/100

x = 2

This means that 5% of 40 is 2. In other words the sales tax of this item is $2

To get the total including sales tax simply add the original price (40) with sales tax (2)

40 + 2 = 42

The total including sales tax is $42

Hope this helped!

$42

Step-by-step explanation:

To find sales tax you need to find 5% of $40.

First, you need to convert 5% to a decimal so its 0.05

Then, multiply 0.05 by $40 which is 2

So the sales tax is $2

Now you need to find how much the total price is with the sales tax.

So you would add $40 and $2, which equals $42

So the total cost of the shoes is $42
