Step-by-step Solution

Vamos resolver o problema passo a passo. 1. **Definindo as variáveis**: - Seja \( C \) o valor que Clara tem. - Então, Marcelo tem \( C - 14 \) (R$ 14,00 a menos que Clara). - E Tenth tem \( C + 20 \) (R$ 20,00 a mais que Clara). 2. **Escrevendo a equação**: - Juntos, eles têm R$ 156,00. Portanto, podemos escrever a seguinte equação: \[ C + (C - 14) + (C + 20) = 156 \] 3. **Simplificando a equação**: \[ C + C - 14 + C + 20 = 156 \] \[ 3C + 6 = 156 \] 4. **Isolando \( C \)**: \[ 3C = 156 - 6 \] \[ 3C = 150 \] \[ C = 50 \] 5. **Calculando os valores de Marcelo e Tenth**: - Clara tem \( C = 50 \). - Marcelo tem \( C - 14 = 50 - 14 = 36 \). - Tenth tem \( C + 20 = 50 + 20 = 70 \). 6. **Resultados**: - Clara: R$ 50,00 - Marcelo: R$ 36,00 - Tenth: R$ 70,00 Portanto, Clara tem R$ 50,00, Marcelo tem R$ 36,00 e Tenth tem R$ 70,00.

Quick Answer

Clara tem R$ 50,00, Marcelo tem R$ 36,00 e Tenth tem R$ 70,00.
