Answer:
12 pounds
Step-by-step explanation:
One quantity is asked for, so it is convenient to let a variable represent that. We can use x to represent pounds of chocolate. Then the total cost of the mix is ...
19.30·x + 3.50·18 = 9.82·(x +18) . . . . cost of chocolate + cost of trail mix
9.48·x = 113.76 . . . . . . simplify, subtract 63+9.82x
113.76/9.48 = x = 12 . . . . . . divide by the coefficient of x
The owner needs to mix 12 pounds of chocolate. (no rounding necessary)
add 3x and 8x to get a sum of 11x and then you cant add 15 to 11x because they dont have the same varuables so your answer is 11x+15
for your answer it is better to keep it in alphabetical order
