Explanation:

Donna

The simple interest formula is given below:

[tex]Simple\;Interest=\frac{Principal\times Rate\times Time}{100}[/tex]

Principal = $80,000, Rate = 3%

[tex]Interest=\frac{80000\times3\times1}{100}=\$2400[/tex]

The interest Donna earns for the first, second, and third years are each $2400.

Tony

1st Year

Principal = $80000, Interest Rate=3%

[tex]Interest=\frac{80000\times3\times1}{100}=\$2400[/tex]

2nd Year

Principal = 80000+2400=$82,400, Interest Rate = 3%

The interest for the second year will be:

[tex]Interest=\frac{82,400\times3\times1}{100}=\operatorname{\$}2,472[/tex]

3rd Year

Principal = 82,400+2472=$84,872

The interest for the third year will be:

[tex]Interest=\frac{84872\times3\times1}{100}=\operatorname{\$}2546.16[/tex]
