$1.90

Explanation:

A ten dollar bill equals $10.00.

The cost of his meal was $8.10, but he paid more than that. The extra money that he paid ($10 minus $8.10) is his change.

Think of it as subtracting a number with a decimal (8.1, which is equivalent to 8.10) from a whole number (10, equivalent to 10.00).

#10-8.1=1.9#

His change is $1.90/1 dollar and ninety cents.
