1ere colonne : 0 | 20 | 500 | 20*500 = 10 000
2eme colonne : 1 | 19 | 550 | 10 450
3eme colonne : 2 | 18 | 600 | 10 800
4eme colonne : 4 | 16 | 700 | 11 200
2) On appelle x le montant de la réduction en euros.
Calculons la recette du spectacle :
(20 - x)(500 + 50x)
Expression développée :
(20 - x)(500 + 50x)
= 20*500 + 20*50x - 500x - 50x²
= 10000 + 1000x - 500x - 50x²
= 10000 + 500x - 50x²
