Steve paid 10% tax on a purchase of $40. select the dollar amount of the tax and the total dollar amount steve paid on the number line.

10 percent of 40 dollars is basically 10 parts out of 100 parts of 40 dollars, which is 4 dollars (0.1(40) = 4). Steve paid 4 dollars in taxes and 44 dollars in total.

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:

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

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
