Find 10% of 40 to find the amount of the tax:

[tex]\sf 40\times 10\%[/tex]

Convert 10% to a decimal

[tex]\sf 40\times 0.1[/tex]

Multiply:

[tex]\sf 4[/tex]

So the amount of the tax is $4. Just add this to the purchase amount to find the total amount he paid:

[tex]\sf 40+4=44[/tex]

So the total amount he paid was $44.

Answer:

Tax= $4

Total payed: $44

Step-by-step explanation:

It´s very simple, you just have to calculate the tax by multiplying the cost of the purchase by the percentage, you just do a rule of thirds:

[tex]\frac{10}{100} =\frac{x}{40}[/tex]

Now we just clear the X to solve for the value of the 10%:

[tex]x=\frac{40*10}{100} \\x=\frac{400}{100} \\x=4[/tex]

So we know that the tax is 10% of $40 which is $4.

The total payed is calculated by adding up the cost plus the taxes:

Total payed= Cost+Taxes

Total payed= $40+$4

Total payed: $44
