Answer:
3. No, due to unilateral mistake
Step-by-step explanation:
Lacey and Cagney both had agreed to wok for 30 hours per week and the agreement is in written format since it is enforceable. Both of them are sharing 50% profits so both will have to share the duties equally. When Lacey makes an excuse and is working for 20 hours per week only Cagney can sues her and she is in a probability to win against her. Lacey should have informed Cagney about the vacation from school scenario before signing the contract.
