Hello! Can you help me solve these questions, please! I'd appreciated!

Thanks so much!

Question1

You plan to invest $10,000 for 180 days. Your bank offers a rate of 2.60% on 90-day GICS and 2.80% on 180-day GICS.

How much more interest will you earn if you purchase a single 180-day GIC instead of two consecutive 90-day GICS? Remember that the interest earned from the first 90-day GIC will be invested in the second 90-day GIC along with the principal.

Express your answer to 2 decimal places but do not include the $ sign.

Question2

Rob has $1,000 to invest for 120 days and is considering two options.

Option 1: He can invest the money in a 120-day GIC paying simple interest of 4.62%.

Option 2: He can invest the money in a 60-day GIC paying simple interest of 4.50% and then re-invest the maturity value into another 60-day GIC. What would the interest rate on the second 60-day GIC have to be for both options to be equivalent? Round your answer to two decimal places and don't include the % symbol.
