Final answer:
Carlos will be paid $144 in interest on his $400 deposit at a simple interest rate of 6% per year over the first 6 years.
Step-by-step explanation:
To calculate how much interest Carlos will be paid in the first 6 years on a $400 deposit at a simple interest rate of 6% per year, we'll use the formula for simple interest:
Simple Interest = Principal × Rate × Time
Where the Principal is $400, the Rate is 0.06 (6%), and the Time is 6 years. Plugging these values into the formula provides the interest Carlos will earn:
Simple Interest = $400 × 0.06 × 6
Simple Interest = $400 × 0.36
Simple Interest = $144
Therefore, Carlos will be paid $144 in interest over the first 6 years.
