Answer:
The exact interest on $5,870 at 12% is $410.9
Step-by-step explanation:
From the information provided we know that
Principal amount: $5,870
Interest rate: 12% -> 0.12
Time: 7 months (From June to December)
When you know the principal amount, the rate, and the time, the amount of interest can be calculated by using the formula:

where P is principal, r is the rate of interest and t is the time in years.
We need to convert the 7 months into 1 year.

Now we can use the above formula

Therefore the exact interest on $5,870 at 12% is $410.9
Answer:
Step-by-step explanation:
To solve this correctly, you need to make sure to distribute the negative onto both terms in the second parentheses.
So fully expanded, the problem would be:
2y² + 8y -7 + 3y - 3 = ?
You can easily rearrange the terms, or just do it in your head!
It would become:
2y² + 8y +3y -7 -3
= 2y² + 11y -10
Make sure you keep the terms with different variables separate! I hope this is helpful!
