If apples are $.67/lb, what is the cost of 2.5 kg of apples?

$3.693

Explanation:

Since an apple costs $0.67 per lb

To get the price for 2.5kg, we need to first convert kg to lb

Since 1kg = 2.205lb

2.5kg = (2.205×2.5)lb

2.5kg = 5.513lb

Since $0.67 = 1lb

$x = 5.513lb

Cross multiplying we have;

x × 1 = 0.67×5.513

x = $3.693

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
