Paul investiu \$966.

Solución

Para encontrar a quantidade que Paul investiu, precisamos usar a relação de investimentos entre Sam e Paul, que é 6:7. Dado que Sam investiu $828, podemos usar a relação para encontrar a quantidade que Paul investiu. Vamos chamar a quantidade que Paul investiu de \( x \). A relação de investimentos é 6:7, então podemos escrever a seguinte equação: \[ \frac{6}{7} = \frac{828}{x} \] Agora, vamos resolver essa equação para encontrar o valor de \( x \), que representa a quantidade que Paul investiu. Solve the equation by following steps: - step0: Solve for \(x\): \(\frac{6}{7}=\frac{828}{x}\) - step1: Find the domain: \(\frac{6}{7}=\frac{828}{x},x\neq 0\) - step2: Swap the sides: \(\frac{828}{x}=\frac{6}{7}\) - step3: Rewrite the expression: \(x=\frac{828\times 7}{6}\) - step4: Divide the terms: \(x=966\) - step5: Check if the solution is in the defined range: \(x=966,x\neq 0\) - step6: Find the intersection: \(x=966\) A quantidade que Paul investiu foi de $966. Portanto, a resposta correta é $966.

To find how much Paul invested, we first need to understand the ratio of their investments. If Sarn's investment is \(6x\) and Paul's investment is \(7x\), and we know Sarn's investment is \$828, we can set up the equation: \(6x = 828\) Now, solving for \(x\): \(x = 828 / 6 = 138\) Now, we can find Paul's investment using \(7x\): \(7x = 7 \times 138 = 966\) Looks like we've made a calculation error. Let's try calculating it again from the ratio: If Sarn's investment is represented as \(6\) parts, and Paul's as \(7\) parts, the total is \(6 + 7 = 13\) parts. We know Sarn's investment of \(6\) parts equals \$828. To find the value of one part, we divide: \(1\) part = \(828 / 6 = 138\) Now we can calculate Paul's investment: Paul's investment, which is \(7\) parts = \(7 \times 138 = 966\) After re-evaluating the calculations, it appears that there was an inconsistency as well with the options. As previously noted, Paul's investment should be \(966\). Thus, based on the options provided and the calculations done so far, the answer must be reviewed, or perhaps there was an intended error in the financial portions extracted. If we categorize this correctly with ratios, the solution may reroute some calculations to achieve accuracy, not the capital formats. Always remember to validate the ratios accurately to ascertain best projections in investments!
