Ticked for a cinema cost £a for adults and £c for children. 2 adults and 3 children cost £42.70. 3 adults and 5 children cost £67.30.
A)use the information to write two simultaneous equations in a and c.
B) How much does it cost for 1 adult and 1 child to go to the cinema?

I would treat it as algebra and for 2 simultaneous equations. dunno if that'll work because i haven't got pen or paper with me right now. So let adults be A and children be B

Step-by-step explanation:

Create 2 Algebraic simultaneous equations.

Step-by-step explanation:

You can make it into a simultaneous equation

To start you off, here are the two equations: 2a+3c=42.70, 3a+5c=67.30

All you need to do is solve for a and c to get the prices for one child and one adult then you add them together to get the final amount
