Answer:
$3
Given data
Let the cost of drinks be x
and the cost of hotdogs be y
so
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
(3, 1), (9, -1), (7, -4), and (1, -2)
(-1, 3), (5, 1), (3, –2), (–3, 0)
+4 +4 +4 +4
(3, 3), (9, 1), (7, -2), (1, 0)
-2 -2 -2 -2
(3, -1), (9, -1), (7, -4), (1, -2)
