Answer:

77 soft drinks were sold

Step-by-step explanation:

let w be the number of water drinks sold, then

number of soft drinks sold is w + 12 ( 12 more sot drinks sold than water )

Total received was $1225 , then

7w + 10(w + 12) = 1225 ← distribute parenthesis and simplify left side

7w + 10w + 120 = 1225

17w + 120 = 1225 ( subtract 120 from both sides )

17w = 1105 ( divide both sides by 17 )

w = 65

That is 65 water drinks were sold and

number of soft drinks sold = w + 12 = 65 + 12 = 77
