John receives $200 for his birthday. He buys 4 DVDs at $12.95 each. Sales tax is 6.25%. How much birthday money does he have left?

4 * 12.95 = $51.80

51.80 * 0.0625 = 3.2375 = $3.24

51.80 + 3.24 = ?

Subtract the sum from $200.

To find out how much birthday money John has left after buying the DVDs, we'll need to calculate the cost of the DVDs and the amount of sales tax, and then subtract those amounts from the $200 he received.

First, let's calculate the cost of the DVDs. John bought 4 DVDs at $12.95 each, so the total cost of the DVDs would be 4 * $12.95.

To calculate the sales tax amount, we need to multiply the total cost of the DVDs by the sales tax rate of 6.25%. Sales tax is usually calculated as a percentage of the cost, so we can use the formula:

Sales Tax Amount = Total Cost of DVDs * Sales Tax Rate

Then, we can calculate the sales tax amount by substituting the values into the formula.

Sales Tax Amount = (4 * $12.95) * 6.25%

Now that we have the cost of the DVDs and the sales tax amount, we can subtract those amounts from the $200 John received to find out how much birthday money he has left.

Birthday Money Left = $200 - (Total Cost of DVDs + Sales Tax Amount)

To get the final answer, substitute the calculated values into the equation.
