Explanation:

In Spanish, the verb "costar" (to cost) has different conjugations. The subject "La cena" (the dinner) is a singular third - person noun. The conjugation of "costar" for singular third - person (él/ella/usted) in the present tense is "cuesta". "cuestas" is the singular second - person (tú) conjugation, and "cuesto" is the singular first - person (yo) conjugation. So, the correct verb form to fill in the blank is "cuesta".
