Klio2033 [76]3 years ago
7 0

Answer:

see below

Step-by-step explanation:

-7(x+2)+4x=6(2x-4)

Distribute

-7x -14 +4x = 12x -24

Combine like terms

-3x-14 = 12x-24

Add 3x to each side

-3x-14+3x = 12x-24+3x

-14 = 15x-24

Add 24 to each side

-14+24 = 15x -24+24

10 = 15x

Divide each side by 15

10/15 =15x/15

2/3 =x

The Chewy Candy Company is test marketing a new candy bar in Seoul and Manila.
Anon25 [30]

The first month in which the board will see the cumulative total number of candy bars sold in Manila exceeded the cumulative total in Seoul is of:

3rd month.

<h3>What are linear functions?</h3>

The slope-intercept definition of a linear function is presented as follows:

y = mx + b.

In which the coefficients are defined as follows:

  • m is the slope, representing the rate of change.
  • b is the y-intercept, representing the initial value.

For the functions in this problem, the slope and the intercept are given as follows:

  • Slope: Monthly increase.
  • Intercept: amount sold by the end of the first month.

Taking the end of the first month as a parameter, the functions are defined as follows:

  • Seoul: S(m) = 40 + 60(m - 1).
  • Manila: M(m) = 20 + 80(m - 1).

Then Manila exceeds Seoul when:

M(m) > S(m)

20 + 80m - 80 > 40 + 60m - 60

20m > 40

m > 2.

2.1 for example is in the 3rd month, hence the 3rd month is the correct answer.
