Number of sodas sold = 130

Number of hot dogs sold = 65

Step-by-step explanation:

Given,

Combined number of sodas and hot dogs sold = 195

Let,

x represent the number of sodas sold

y represent the number of hot dogs sold

According to given statement;

x+y=195 Eqn 1

x = 2y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$2y+y=195\\3y=195$

Dividing both sides by 3

$\frac{3y}{3}=\frac{195}{3}\\y=65$

Putting y=65 in Eqn 2

$x=2(65)\\x=130$

Number of sodas sold = 130

Number of hot dogs sold = 65
