Answer:
#3. d = -10.25
Step-by-step explanation:
#3. d = -6.5 + -3.75
step by step explanation:
Add 1 to both sides
52x−1+1=12x+1
Simplify
52x=12x+1
Subtract 12x from both sides
52x−12x=12x+1−12x
Simplify
40x=1
Divide both sides by 40
40x40 =140
Simplify
x=140
Answer:
8200/1000 = 8.2 so each time a class sells 8.2 bars, they receive 1 dollar.
If a class sold 16 bars, the class receives 2 dollars, if it sold 82 bars, it receives 10 dollars and so on.
