The question asks you to write an algebraic expression to represent the amount of money she earns for one table:
$2(1) + 0.20(c) = m
Explanation:
She earns $2 per table and she's serving one table, so it would be $2(1)
and then she also earns 20% of the total customer order, so it would be
+ 0.20(c), c stands for the customer order
and m would represent the amount of money she earned
