We are given two equations with two unknowns so definitely we have a unique answer.

The shortest way to the answer of ( what is the cost of two sodas) is to eliminate the hot dogs from the equations.

2H + 1S = \$3.25
3H + 1S = \$4.50

Multiply the equations to make the coefficient of H same ( which will be the LCM of 2 and 3 = 6)

6H + 3S = \$9.75
6H + 2S = \$9

On subtraction -
S = \$0.75

So 2S = \$1.5

Option (C) is correct.

simplify given info
let hotdog x and soda y
2x+y=3.25
3x+y=4.5
solve for x = 1.25
and
y = 0.75
2 soda = 0.75*2 = 1.5 IMO C
