Question
c. abbie spent \\(\frac{5}{8}\\) of her money and saved the rest. if she spent $45, how much money did abbie start with?
Step1: Definir la variable
Sea \( x \) la cantidad de dinero inicial que tenía Abbie.
Step2: Establecer la ecuación
Sabemos que \(\frac{5}{8}\) de su dinero es igual a \$45, por lo tanto:
\(\frac{5}{8}x = 45\)
Step3: Resolver la ecuación para \( x \)
Multiplicar ambos lados por \(\frac{8}{5}\) para aislar \( x \):
\( x = 45 \times \frac{8}{5} \)
Simplificar la operación:
\( 45 \div 5 = 9 \), entonces \( 9 \times 8 = 72 \)
