Question

at a football game, a vender sold a combined totalf of 248 sodas and hot dogs. the number of sodas sold was three times the number of hot dogs sold. find the number of sodas and hot dogs sold.

Answer 1

Number of soda = 186

Number of hot dog= 62

Explanation:

Let us take number of sodas as x and number of hot dogs as y

Then

x + y = 248 [Equation 1]

and

3y = x

Hence,

3y -x = 0 [Equation 2]

By adding [Equation 1 & 2]

(+x -x) 3y + y = 248 + 0

4y = 248

4 4

y = 62

Substitute y= 62 in [Equation 1] to get

x + y = 248

x + 62 = 248

x = 248 - 62

x = 186
