Solution:

Let the number of three-point attempts be $t.$

Then, the number of made three-point shots is $0.4 t,$ implying that the number of points made off of three-point shots is $1.2t.$

Similarly, the number of two-point shots is $1.5t,$ so the number of made two-point shots is $0.75t,$ giving $1.5t$ points from two-point shots.

This makes the total number of points scored equal to: $2.7t=54,$ and so, $t=20.$

Thus, the correct answer is C .
