Answer:
See below
Step-by-step explanation:
Let the number of Payday be p and Baby Ruth be b
<u>Then sub of the candy bars:</u>
- Payday candy bars worth ⇒ $2p
- Baby Ruth candy bars worth ⇒ $3b
- Total ⇒ $600
1. <u>Required equations:</u>
2. <u>Solving by substitution:</u>
p = 220 - b, consider it in the second equation
- 2(220 - b) + 3b = 600
- 660 - 2b + 3b = 600
- 660 + b = 600
- b = 660 - 600
- b = 60
60 Baby Ruth candy bars sold
Answer: C is correct, 4x=8
Step-by-step explanation:
You will add the two equations...
4x-8=0
Now you need to move the -8 over, which reverses its sign to positive.
4x=8
Money spent + money left over = total money
money spent + 9 = 30
We don't know the price of each shirt, so let x = price of 1 shirt.
Then, 3 shirts cost 3 times as much as x, or 3x.
She spent 3x.
3x + 9 = 30
