<u>Answer:</u>

Amount collected in 2012 = 3.49

and in 2013 = 3.35

<u>Explanation:</u>

Let x be the baggage fees collected in 2013 and

y be the baggage fees collected by airlines in 2012

From the given question we can obtain two equations as follows:

x + y = 6.84 $   - eq 1

and

y = 0.14 + x

as fees in 2012 exceeds that in 2013 by 0.14$

Now, solving these two equations by substitution,

we substitute  y = 0.14 + x in eq 1

and solve for x,

which gives us x = 3.35 and

substituting this value in eq 1

we get y = 3.49

Lyrx [107]
People with kids or babies always want them to eat natural foods with no preservation, even if are a bit more expensive than the other available options.What they care about is the quality and health of the kids.So keeping this point in head,most of the brands uses the technique to compete with the other in-market brands. And that's what the shopkeeper did in this case.
Mike should have read the listed ingredients on the baby food jar.I think both of them would have the same,except a few.

1)What value for y makes the equation 2(y-4)+8=12+y true?
NemiM [27]

Answer:

1. Option B- y=12

2. Option D - 2

Step-by-step explanation:

1. 2(y - 4) + 8 = 12 + y

  2y - 8 + 8 = 12 + y

add like terms -8 + 8 is 0 so

2y = 12 + y

Subtract y

1y = 12

Divide by 1

y= 12

2. -4(2) - 6  > -14

    -8 - 6 > -14

      -14 > -14

    This is not true because -14 is not greater than -14, they are equal.

Hope this helps.
