Answer
1. Simple Interest
Explanation:
Step1: Identificar la fórmula
La fórmula de interés simple es $I = Prt$, donde $P$ es el principal, $r$ es la tasa de interés anual y $t$ es el tiempo en años.
Step2: Sustituir valores
$P = 1200$, $r=0.03$ (3% expresado como decimal) y $t = 4$. Entonces $I=1200\times0.03\times4$.
Step3: Calcular
$I = 144$.
Answer:
$144$
2. Monthly Budgeting
Explanation:
Step1: Calcular ahorros
El 40% de 800 para ahorros. $0.4\times800 = 320$.
Step2: Calcular gastos diarios
El 35% de 800 para gastos diarios. $0.35\times800=280$.
Step3: Calcular entretenimiento
El 25% de 800 para entretenimiento. $0.25\times800 = 200$.
Answer:
Ahorros: $320$ Gastos diarios: $280$ Entretenimiento: $200$
3. Compound Interest
Explanation:
Step1: Identificar la fórmula
La fórmula de interés compuesto es $A=P(1 + r)^t$, donde $A$ es el monto final, $P$ es el principal, $r$ es la tasa de interés anual y $t$ es el tiempo en años.
Step2: Sustituir valores
$P = 2000$, $r = 0.05$ (5% expresado como decimal) y $t=3$. Entonces $A = 2000\times(1 + 0.05)^3$.
Step3: Calcular
$(1 + 0.05)^3=1.05^3 = 1.157625$. Luego $A=2000\times1.157625=2315.25$.
Answer:
$2315.25$
4. Interest Rate
Explanation:
Step1: Convertir fracciones a decimales
$5\frac{1}{10}%=5.1% = 0.051$, $5\frac{1}{4}%=5.25%=0.0525$, $5\frac{2}{5}%=5.4% = 0.054$.
Step2: Comparar valores
Tenemos $0.051$, $0.0522$, $0.0525$, $0.0528$, $0.054$. El mayor valor es $0.054$ que corresponde a $5\frac{2}{5}%$.
Answer:
$5\frac{2}{5}%$
