Hayden invested $750 for 3 years at an interest rate of 0.035 how much interest did he earn in that time

78.75 (simple)    81.54 (compound)

Step-by-step explanation:

Simple interest without compounding : I = P * (1 + rt) -P  

I: interest         P: primary investment       r: annual rate   t: time in year

I = =750 * (1+ 0.035*3) -750 =  78.75

Compound interest      I = （P *（1 +r）^ t）-P

I' = 750*(1+0.035)*(1+0.035)*(1+0.035) - 750 = 81.54

the equivalent expression are always the hardest ones but you look at the gcf also
