a) 24% said they wanted to learn french.
To find total number of students surveyed divide the number of students that want to learn French by the percentage:
12 / 0.24 = 50
There were 50 students surveyed.
b) 36% wanted to learn Spanish, multiply 50 by 36%
50 * 0.36 = 18
18 students wanted to learn Spanish.
30×30=900
900/112.5=8 cameras to cover
112.5×4=450
900-450=450 ft left uncovered
