Price tags with dollars and cents
Dollars before the point, ten-cents just after it.
How to do it
Method
Dollars before the point, ten-cents just after it
$23.50 = $23 and 5 ten-cents = 235 ten-cents
Another way
All in ten-cents
25 + 18 = 43 → $4.30
In full
On a price tag like $23.50, the part before the point is dollars and the first digit after it is ten-cent pieces: twenty-three dollars fifty. 1 dollar = 10 of those, so $23.50 is 235 ten-cent pieces. Writing a price, the ten-cents go in the first place after the point and a 0 in the second: $7 and 3 ten-cents is $7.30, not $7.03. To compare prices, compare the dollars, then the ten-cents. Or change everything to ten-cents first: $2.50 + $1.80 = 25 + 18 = 43 ten-cents = $4.30.
