The point EEE represent option b is correct: Marcelina spends the intended amount of money but she bought more than she did intended amount of corn.
She buy 50kg of corn in total
White corn costs = $0.30 per kilogram,
Yellow corn costs = $0.15 per kilogram,
She wants to spend $12 total.
So the equation will be:
C= (20, 50) = 20 white, 50 yellow
But 30 while and 20 yellow is needed.
Since C = 20 +50
= 70 corns
While: 30 + 20
= 50 corns.
This therefore tells that Marcelina spends the intended amount of money but she bought more than she did intended amount of corn and therefore, option b is correct.
