OpenStudy (welshfella):
so which 2 of the choices can be correct?
OpenStudy (isuckatschool43):
C and D
OpenStudy (welshfella):
it must be C or D yes
OpenStudy (welshfella):
now c is the number of child tickets and they cost $3 each
so cost of all child tickets = 3 * c which we can write as
3c
sso now you should be able to find which one C or D
OpenStudy (isuckatschool43):
so D
