HI!!

misty1212 · Answer

looks like they are trying to make this as complicated as possible huh?

shaik0124 · Answer

a=50+2*c  from given data

misty1212 · Answer

you need two variables, one for  the number of child's tickets and one for adult tickets
do you have answer choices or can you make them up?
