Flora Hall signed an agreement with Rent$-$A$-$Center to make monthly payments of $$77\mathrm{.}96$ for $19$ months in exchange for her to have a washer and dryer in her home. The agreement required her to pay tax and a liability waiver fee. The total amount she would pay under the agreement is $$1,643\mathrm{.}15.$

At any time during the $19$ months, Flora could return the washer and dryer, or at the end of making $19$ months of payments could pay an additional $$161\mathrm{.}91$ and own them.

Is this a sales contract?

Is this a consumer lease?

Must this agreement be in writing?
