what’s the better value 1/2 kg of bulk sunflower seeds costing $.70 per 100 grams or A 500 mg bag of prepackage seeds costing $3
PilotLPTM [1.2K]

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.
