Answer 1

The cost for 3.75 kg of chocolate, based on a proportion with 0.7 kg costing $4.20, is calculated to be $22.50, which is answer choice (d).

Step-by-step explanation:

To solve this problem, we can set up a proportion based on the given information. Since 0.7 kg of chocolate costs $4.20, we can set up the proportion like so:

0.7 kg / $4.20 = 3.75 kg / x dollars

Where x represents the cost of 3.75 kg of chocolate. Now, we cross multiply:

0.7 * x = 3.75 * $4.20

This simplifies to:

x = (3.75 * $4.20) / 0.7

After performing the calculation:

x = $22.50

So, the main answer is that 3.75 kg of chocolate would cost $22.50.
