Answer 1

Inicialmente a conta possui um saldo de R$438,40.

a) O saldo (S) sera:

$\mathsf{S_a=439,40-123-97,51-200}\\\\\mathsf{S_a=239,40-123-97,51}\\\\\mathsf{S_a=239,40-220,51}\\\\\boxed{\mathsf{S_a=R\ \:18,89}}\: \: \checkmark$

b) O saldo (S) sera:

$\mathsf{S_b=S_a-82,60-50}\\\\\mathsf{S_b=18,89-82,60-50}\\\\\mathsf{S_b=18,89-32,60}\\\\\boxed{\mathsf{S_b=R\ \:-13,71}}\: \: \checkmark$

c) O Saldo (S) sera:

$\mathsf{S_c=S_b+115,29}\\\\\mathsf{S_c=-13,71+115,29}\\\\\boxed{\mathsf{S_c=R\ \:101,58}}\: \: \checkmark$

O Saldo depois de todas as operações sera: $\boxed{\boxed{\mathsf{R\ \:101,58}}}$
