Bonnie and Clyde

Bond Bonnie: Par value $$5,000,$ coupon $6\%$ semi$-$annual, maturity $2$ years, trades today for $$4,500.$

Bond Clyde: Par value $$5,000,$ coupon $6\%$ semi$-$annual, maturity $25$ years, trades today for $$4,200.$

What would be the impact on the price of the two bonds, if the interest rate drops or increases by $2?$

What do you infer from this problem regarding the interest rate risk?

If you could show it using Excel or the formula for that I will be greatful
