Responder:
$ 16,2
Explicação passo a passo:
No dia da festa, Bianca comprou os pastéis por US $ 5,20, duas maçãs do amor por US $ 3,40 e dois refrigerantes por US $ 7,60. Quanto bianca você gastou?
O valor gasto por Bianca é a soma de todos os itens que ela comprou:
Pastelaria = $ 5,20
Maçãs do amor = $ 3,40
Refrigerantes = $ 7,60
A soma da soma dá o valor gasto de Bianca:
Doces + Maçãs do Amor + Refrigerante
$ (5,20 + 3,40 + 7,60)
= $ 16,2
