Answer:
$1.57
Step-by-step explanation:
lets use the expression [tex]a(1+r)^t[/tex]
where a is the initial amount, r it the rate, and t is time
Leah: initial amount = 100, r = 2.5% = 0.025, t = 3
100(1.025)^3= 107.69
Marty: initial amount = 100, r = 2% = 0.02, t = 3
100(1.02)^3= 106.12
difference:
107.69 - 106.12 = 1.57
