Answer:
A 500 mg bag of prepackage seeds costing $3.95
Step-by-step explanation:
First, you need to know the amoun of grams in 1/2 kg to find the cost of the sunflower seeds:
1 kg→1000 grams
1/2 kg→ x
x=(1000*(1/2))/1
x= 1000/2
x= 500 grams
Second, you have to find the cost of 500 grams of sunflower seeds:
100 grams → $0.70
500 grams→ x
x=(500 *0.70)/100
x= 3.5
According to this, 1/2 kg of of bulk sunflower seeds cost $3.5 which is cheaper than the 500 mg bag of prepackage seeds that cost $3.95 and this means that the better value is 1/2 kg of bulk sunflower seeds as the amount is also higher as 500 mg is equal to 0.5 grams.
