mrs asma paid Dh202.50 for a group of 9 students in visit an amusement park what would the total cost be if 4 more students wanted in join the group
+37084 Find out the 'unit cost ' per student then multiply by (9+4more)
unit cost = 202.50/9 = 22.5 /student
22.5/student x (9+4)students = 292.50 total cost
