Respuesta :
All size bags have the same constant of proportionality, therefore, it doesn't matter which size bag she chooses
Answer:
Step-by-step explanation:
Nellie wants to buy bird seed to put in her bird feeders.
The bird seed comes in 3 different sizes :
Bag of 3.5 pounds for = $2.52
cost per pound = [tex]\frac{2.52}{3.5}[/tex] = $0.72
Bag of 7.5 pounds for = $5.40
cost per pound = [tex]\frac{5.40}{7.5}[/tex] = $0.72
Bag of 11 pounds for = $7.92
cost per pound = [tex]\frac{7.92}{11}[/tex] = $0.72
Per pound cost of bird seeds is same so it does not matter which size of the bag Nellie purchase.
She may buy 3 bags of 3.5 pounds or 1 bags of 7.5 pounds with 1 bag of 3.5 pounds or 1 bag of 11 pounds for a week.
