Option C is correct.
Alex earned about $60 more than Joaquin did.
Step-by-step explanation:
The linear regression equation
y = 0.18 x + 320.22
is used to predict the weekly salary, y, of an employee who sells x dollars worth of merchandise.
Joaquin sold $1500 worth of goods. Meaning that x for that week for Joaquin is 1500.
Joaquin' s salary for that week is then given as
y = 0.18x + 320.22
y = 0.18(1500) + 320.22 = 590.22
Hence, Joaquin's salary for that week = $590.22
Alex earns $650 that week. Meaning that y for Alex in that week = 650
y = 0.18x + 320.22
650 = 0.18x + 320.22
0.18x = 650 - 320.22 = 329.78
x = (329.78/0.18) = 1832.1
Hence, Alex sold goods worth $1832.1 that week.
Joaquin sold goods worth $1500
Joaquin earned $590.22
Alex sold goods worth $1832.1
Alex earned $650
From this calculation, it is evident that 'Alex earned about $60 more than Joaquin did' is the correct option as $650 is about $60 more than $590.22
Hope this Helps!!!
