Answer

Explanation:

Step1: Encontrar el precio de un boleto

Observando la gráfica, cuando $x = 10$ (número de boletos vendidos), $y = 50$ (dinero recaudado). El precio de un boleto es $\frac{50}{10}=5$ dólares.

Step2: Calcular el dinero recaudado con 20 boletos

Con 20 boletos vendidos, el dinero recaudado es $20\times5 = 100$ dólares.

Step3: Calcular el dinero faltante

El costo de los suministros es 175 dólares. El dinero faltante es $175 - 100=75$ dólares.

Step4: Calcular el número de boletos adicionales

Dado que cada boleto cuesta 5 dólares, el número de boletos adicionales es $\frac{75}{5}=15$.

Answer:

15
