Sorry the answer to Q3 got jumbled up.
This is the correct version.
Ignore the …

Some help needed for this question too. Thanks for the kind help rendered.


Mrs Lim buys 3 kg of beef and has $15 left. If she wants to buy 4 kg of beef, she would need $3 more. How much money does Mrs Lim have?

Hi

To buy 4kg = buying 1 kg more.. so, Mrs Lim needs $ 15 + $ 3 = $18 for 1kg more ie 1kg of beef cost $ 18... I think you can continue from here

cheers.
