the soccer team collected $800 at a car wash fundraiser. they charged $5.00 for small vehicles and $10.00 for larger vehicles. the amount collected can be modeled by the equation 5x + 10y = 800, where x represents the number of small vehicles and y represents the number of larger vehicles. if the number of larger vehicles washed was 50, how many small vehicles were washed in total?\no 55\no 60\no 130\no 150
Answer
Answer:
B. 60
Explanation:
Step1: Sustituir el valor de y
Dado que $y = 50$, sustituimos en la ecuación $5x+10y = 800$. Obtenemos $5x+10\times50 = 800$.
Step2: Simplificar la ecuación
$5x+500 = 800$. Restamos 500 de ambos lados: $5x=800 - 500$, entonces $5x = 300$.
Step3: Resolver para x
Dividimos ambos lados de la ecuación $5x = 300$ por 5. Tenemos $x=\frac{300}{5}=60$.
