A van can ferry a maximum of 12 people. by setting up an inequality, find the number of vans that are needed to ferry 80 people.​

answer: the answer is given below.

step-by-step explanation: we are given to explain the importance of written contract over oral contract.

in oral contract, we cannot show the terms and conditions of the contract to a third party or person. that is, any of the two parties can anytime decline the agreement.

but, in written contract, we have all the proofs that both the parties agreed to a particular condition in addition to the signatures of both of them. so, we can always show the written proofs to any person or party.

thus, written contract is always better than the oral one.
