At a baseball game, a vender sold a combined total of 214 sodas and hot dogs. The number of hot dogs sold was 34 less than the n

Archy [21]

The vendor sold 124 sodas and 90 hot dogs.

Step-by-step explanation:

Let,

x be the number of sodas.

y be the number of hot dogs.

Total sold = 214

According to given statement;

x+y=214 Eqn 1

y= x-34 Eqn 2

Putting value of Eqn 2 in Eqn 1;

$x+(x-34)=214\\x+x-34=214\\2x=214+34\\2x=248$

Dividing both sides by 2;

$\frac{2x}{2}=\frac{248}{2}\\x=124$

Putting x=124 in Eqn 2;

$y=124-34\\y=90$

The vendor sold 124 sodas and 90 hot dogs.
