Answer 1

Resposta:  4%a.m.

Explicação passo a passo:

Juros simples

180d=6m

i=j*100/C/t

i=1200*100/5000/6

i=120000/5000/6

i=24/6

i=4

Answer 2

$> resolucao \\ \\ \geqslant juros \: \: simples \\ \\ c = 5.000.00 \\ j = 1.200.00 \\ t > 180 \: dias > \frac{180}{30} = 6 \: meses \\ \\ \\ j = \frac{c \times i \times t}{100} \\ \\ 1200 = \frac{5000 \times i \times 6}{100} \\ \\ 1200 = 50 \times i \times 6 \\ \\ 1200 = 300 \times i \\ \\ i = \frac{1200}{300} \\ \\ i = 4 \\ \\ \\ resposta \: > \: \: taxa \: de \: 4\%a.m \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \geqslant \geqslant$
