Respuesta :

Answer:

In 28 days George have the same amount of candy as Penelope.

Step-by-step explanation:

Given:

Penelope has 152 pieces of candy.

George has 124 pieces of candy.

Penelope eats 5 pieces each day.

George eats 4 pieces each day.

To find in how many days will George have the same amount of candy as Penelope.

Solution:

Let the number of days in which George have the same amount of candy as Penelope be = [tex]x[/tex]

Using unitary method.

If Penelope eat 5 pieces of candy in 1 day.

In [tex]x[/tex] days, he will eat = [tex]5x[/tex] candies

Thus, after [tex]x[/tex] days number of candies left with Penelope = [tex]152-5x[/tex]

If George eat 4 pieces of candy in 1 day.

In [tex]x[/tex] days, he will eat = [tex]4x[/tex] candies

Thus, after [tex]x[/tex] days number of candies left with George = [tex]124-4x[/tex]

Since, in [tex]x[/tex] days George have the same amount of candy as Penelope, so we have:

[tex]124-4x=152-5x[/tex]

Solving for [tex]x[/tex]

Adding [tex]5x[/tex] both sides.

[tex]124-4x+5x=152-5x+5x[/tex]

[tex]124+x=152[/tex]

Subtracting 124 both sides.

[tex]124-124+x=152-124[/tex]

∴ [tex]x=28[/tex]

Thus, in 28 days George have the same amount of candy as Penelope.
