Mercury · Answer

missing equation: y = 0.18 x + 320.22

in this case, y represents the salary and x represents the amount of merchandise sold

Joaquin sold $1500 worth of merchandise. ---> plug in x = 1500 and find Joaquin's y-value
The same week, Alex earned $650.  ---> plug in y = 650 and find Alex's x-value.

once you have both their salaries and merch sold amounts, you can compare them and see which statement is true.
