Q #1: There are 800 students enrolled in four allied health program at a local community college. The percent students in each program is displayed in the pie chart. Which of the following is the number of students enrolled in the dental hygiene program?

A. 168

B. 144

C. 336

D. 152

We solve the value of x by cross-products.

Therefore, 144 students will enroll for a dental hygiene program.
