Step-by-step explanation:

total sold = 136

hot dogs sold : soda - 30

136 = soda + hot dogs

136 = soda + (soda -30)

136 = 2soda -30

2soda = 166

soda sold = 83

hot dogs sold = 83-30 = 53

Answer:

Number of soda's sold = 83

Number of hot dogs sold = 53

Step-by-step explanation:

Let the number of soda's sold =s

Number of hot dogs sold = h

s +h = 136  --------------(I)

h = s - 30 ---------------(II)

Substitute h =s -30  in equation (I)

s + s - 30 = 136

Combine like terms

2s - 30 = 136

Add 30 to both sides

2s = 136 + 30

2s = 166

Divide both sides by 2

s = 166/2

S = 83

Plugin s = 84 in equation (II)

h = 83 - 30

h = 53
