Pilar and her sister Marisol live near the beach. Pilar has 80 seashells in her collection when Marisol started collecting seashells. Marisol started with zero seashells in her collection.

• Pilar adds 10 seashells to her collection each week for x weeks. • Marisol adds 20 seashells to her collection each week for x weeks.

Write AND Solve the equation
that represent the situation when the number of seashells in Marisol's collection is the same as the number of seashells in Pilar's collection. ​

Respuesta :

The number of weeks is represented by x

  • Pilar has 80 seashells in her collection, Pilar adds 10 seashells to her collection each week for x weeks.

The algebraic expression for Pilar's seashell collection is :

= 80 + 10x

  • Marisol started with zero seashells in her collection. Marisol adds 20 seashells to her collection each week for x weeks.

The algebraic expression for Pilar's seashell collection is :

= 0 + 20x

= 20x

The equation  that represents the situation when the number of seashells in Marisol's collection is the same as the number of seashells in Pilar's collection is written as:

Marisol  = Pilar

20x = 80 + 10x

Collect like terms

20x - 10x = 80

10x = 80

Divide both sides by 10

10x/10 = 80/10

x = 8

Therefore, the number of weeks when the number of seashells in Marisol's collection is the same as the number of seashells in Pilar's collection is 8 weeks.
