Before the point: dollars; just after: ten-cents.
How to do it
Method
Before the point: dollars; just after: ten-cents
$2.50 = 2 dollars 50 cents
Another way
All in ten-cents
$2.50 = 25 ten-cents
In full
On a price tag, $ means dollars. The number before the point is dollars, and the first digit after it is ten-cents: $2.50 is read “two dollars fifty”, $3.00 is three dollars exactly, $0.80 is eighty cents. To compare prices, compare the dollars first, then the ten-cents if the dollars match. To pay, give the dollars, then the ten-cents: $2.50 can be 2 one-dollar coins and a fifty-cent coin. Or turn it all into ten-cents to compare: $2.50 is 25 ten-cents.
