$\$20.75$
Work Step by Step
$2(\$6.25) + 1(\$5.50) + 2(\$2.75) = \$20.75$
The cost of 1 salad is \$6.25, so the cost of 2 salads is twice that, which is \$12.50. The cost of 1 sandwich is \$5.50. The cost of 1 drink is \$2.75, so the cost of 2 drinks is twice that, which is \$5.50. The total cost is the sum of all of these values, which is \$20.75.
