Answer:
Mara did not divide correctly
Step-by-step explanation:
I = p r t
P = 4300
r = 6.2 % = 0.062
t = ?
I = 2666
=> 2666 = 4300 (0.062) * t
Mara substitute the values from the problem into the formula correctly
=> 2666 = 266.6 * t
Mara multiply correctly
=> 2666/266.6 = t ( but Mara Wrote 266.6/2666 = t)
hence Mara Did not divided correctly
=> 10 = t
Mara Did not divided correctly
