Final answer:
The cost of avocados at different quantities can be calculated using basic multiplication and division. 16 avocados cost $8, 20 avocados cost $10, one avocado costs $0.50, and with $12, you can buy 24 avocados.
Step-by-step explanation:
To solve these questions, we'll apply basic arithmetic to determine the cost of avocados given their price and quantity. We know that eight avocados cost $4, so we can calculate the price per avocado and then use that to find out the cost for different quantities of avocados.
- 16 avocados: Since eight avocados cost $4, 16 avocados (which is double the amount) will also cost double, so 16 avocados will cost $8.
- 20 avocados: First, we find the cost of one avocado by dividing $4 by 8, which gives us $0.50 per avocado. Then we multiply $0.50 by 20 to find the cost for 20 avocados, which is $10.
- 1 avocado: As calculated above, one avocado costs $0.50.
- Avocados with $12: Given $12 and knowing one avocado costs $0.50, we can divide $12 by $0.50 to determine the number of avocados you can buy, which is 24 avocados.
