At a baseball game, 3 drinks and 4 hotdogs cost $15.00. At the same game, 3 drinks and 1 hotdog cost $10.50. Find the cost for a

Serhud [2]

Answer:

Step-by-step explanation:

Given data

Let the cost of drinks be x

and the cost of hotdogs be y

3x+4y=15-------1

also

3x+y= 10.5------2

solve 1 and 2

3x+4y=15

-3x+y= 10.5

3y= 4.5

divide both sides by 3

y= 4.5/3

y= $1.5

Put y= 1.5 in 1

3x+4(1.5)=15

3x+6= 15

3x=15-6

3x= 9

x= 9/3

x= $3

Hence the cost of a drink is $3
