Final answer:
To find the cost of 3 bags of flour, each holding 1.5kg, convert the weight to grams. Then, use a proportion to find the cost of 1500 grams of flour. The cost of 3 bags will be $102.00.
Step-by-step explanation:
To find the cost of 3 bags of flour, each holding 1.5kg, we first need to convert the weight of the bags to grams. Since 1 kilogram is equal to 1000 grams, each bag contains 1.5kg x 1000g/kg = 1500 grams of flour.
To find the cost of 1500 grams of flour, we can use a proportion. We know that 250 grams of flour cost $17.00. So, for 1500 grams of flour, the cost would be (1500g/250g) x $17.00 = $102.00
Therefore, 3 bags, each holding 1.5kg of flour, will cost $102.00.
