"If you were buying nuts, would you rather pay $9/kg or $4/500 g?Explain."

since 500 g is 1/2 kg

the second would sell for $8 / kg.

59+38+59+90

To determine which option is more cost-effective when buying nuts, we need to compare the prices per unit of weight. Here's how we can do it:

1. For the first option: $9/kg.
To compare this price with the second option, we need to convert the units to match. Since there are 1000 grams in a kilogram, we'll divide the price by 1000 to find the cost per gram:
$9/kg ÷ 1000 g = $0.009/g

2. For the second option: $4/500 g.
Here, the price is already given in grams, so we don't need to convert it.

Now, we can compare the prices per gram:
$0.009/g (Option 1) vs. $4/500 g (Option 2).

To make a fair comparison, we need to convert Option 2 to price per gram. Since 500 grams is half a kilogram (0.5 kg), we'll divide the cost by 0.5:
$4/500 g ÷ 0.5 kg = $8/kg.

Now we can compare the prices directly:
$0.009/g (Option 1) vs. $8/kg (Option 2).

From the comparison, we can see that Option 1 is cheaper. It costs $0.009 per gram, while Option 2 costs $8 per kilogram. Therefore, if you were buying nuts, it would be more cost-effective to choose the option of paying $9/kg.
