Question

Wendy earns $2 for every table she serves [lus 20% of the total customer order. Define a variable and write and expresion to represent the amount of money she earns for one table

Answer 1

So Wendy makes $2 every table so it's the constant bc she will always make exactly $2 for each table she serves. 20% of the customer order is the variable bc not all customer orders will be a different amount. 20% is 0.20 in decimal form
so if y is the amount of money she earns and x is the amount of the customer order then
y=2+0.20x
