Answer:
express and bilateral contract
Explanation:
An express contract is a contract in which the parties involved have carefully and explicitly/openly set the terms of the contract.
This contract contains agreements of both parties either verbally or in writing. Express contracts are also called Special contracts.
from the question, Todd's offer to shovel Maria's patio for a fee and her acceptance of the fee for the job is an express contract as it is oral.
A bilateral contract on the other hand is a contract in which both parties involved agree to their part of the contract. In the case of the question, Todd's part is to shovel Maria's patio while Maria's part of the contract is to pay Todd $25 for the job.
I hope this helps.
