This question is basically asking
"what is $7.25 times 30?"We can break the $7.25 down into 7 dollars and 25 cents, and then multiply each by 30...
the 7 dollars × 30 = 210 dollars, and
the 25 cents × 30 = 750 cents = 7.50
210 + 7.50 =
$217.50You could also do decimal multiplication like this:

You just multiply like a normal number, but line up the decimal points and add in zeroes as a placeholder for the 30 past the decimal point. I left out the lines of multiplying the first three zeroes because it is fairly obvious...Once you have your result you put your decimal point 4 places from the right because it should reflect the 2 from the 30.00 plus the 2 from the 7.25.
