Answer:

R$49.02

R$49.09

Step-by-step explanation:

Por não pagar a conta em dia, o valor de 2% de juros foi adicionado, o novo valor base passa a ser:

V = 1.02*48\\V=R\$48.96

O valor a ser pago n dias após o dia 13 de abril é dado por:

P=48.96*(1+\frac{0.033}{100} )^n

No dia 17 de abril, n =4 e o valor a ser pago é:

P=48.96*(1+\frac{0.033}{100} )^4\\P=R\$49.02

Caso n =8, o valor a ser pago seria:

P=48.96*(1+\frac{0.033}{100} )^8\\P=R\$49.09
