Hi. My friend and I are discussing a problem and we could not find the answer.

"In a biology class, a student with a near-point distance of 25 cm, uses a microscope to view an amoeba. If the objective has a focal length of 0.5 cm, the eyepiece has a focal length of 2.5 cm, and the amoeba is 1.5 cm from the objective, what is the magnification produced by the microscope?"

a.30

b. 15

c. 22

d. 2.5

e. 28

I think the answer should be 30, my friend thinks it should be 2.5

Thank you for helping us out
