OpenStudy (isuckatschool43):

OpenStudy (welshfella):

number of child tickets + number of adults = a + c = what?

OpenStudy (welshfella):

- the answer is in the question

OpenStudy (isuckatschool43):

115?

OpenStudy (isuckatschool43):

wait 3

OpenStudy (welshfella):

No thats the cost of the tickets

OpenStudy (welshfella):

no not 3

OpenStudy (welshfella):

how many tickets were sold?

OpenStudy (isuckatschool43):

33

OpenStudy (isuckatschool43):

i think D right? pretty sure

OpenStudy (welshfella):

right

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

OpenStudy (welshfella):

correct 3c + 5d = 115

OpenStudy (isuckatschool43):

OpenStudy (isuckatschool43):

oops

OpenStudy (isuckatschool43):

OpenStudy (welshfella):

this is very similar to the last question try and figure it out yourself

OpenStudy (welshfella):

one part is easy total score = 187 so we get d + g = 187

OpenStudy (isuckatschool43):

A?

OpenStudy (welshfella):

desmonds score less than georges SO d = g - 3 yes A is correct

OpenStudy (welshfella):

gtg

OpenStudy (isuckatschool43):
