The total cost of the hamburger meat is $5.00.
The total cost of the box of crackers is $3.50.
The total cost of the 4 bags of frozen vegetables is 4 * $2.00 = $8.00.
The total cost of the pack of cheese is $3.50.
The subtotal of Ray's purchase is $5.00 + $3.50 + $8.00 + $3.50 = $20.00.
Ray is a store rewards member and gets a 10% discount on his purchase, so the discount amount is 10% of $20.00, which is 0.10 * $20.00 = $2.00.
The total amount of Ray's grocery bill after the discount is $20.00 - $2.00 = $18.00.
