Final answer:
To find out how much money each of them invested, we can use the given ratio and divide the total amount by the parts in the ratio. Spongebob invested $24,000, Patrick invested $14,000, and Mr. Krabs invested $32,000.
Step-by-step explanation:
To find out how much money each of them invested, we need to use the given ratio of 12:7-16. Let's start by adding the numbers in the ratio: 12 + 7 + 16 = 35. This means that the total ratio is divided into 35 parts.
To find out the amount of money each person invested, we need to divide $70,000 by 35: $70,000 / 35 = $2,000 per part.
Now, we can calculate the investment for each person by multiplying their part in the ratio by the amount per part:
Spongebob: 12 parts x $2,000 per part = $24,000
Patrick: 7 parts x $2,000 per part = $14,000
Mr. Krabs: 16 parts x $2,000 per part = $32,000
