Question

sarah wants to write a word problem using the model below. which best describes sarah’s problem? a. sarah has 4 friends. she wants to give each friend three cookies. sarah needs to make 12 cookies. b. sarah has 12 friends. she wants to give each friend four cookies. sarah needs to make 48 cookies. c. sarah has four friends. she wants to give each friend 4 cookies. she needs to make 16 cookies. d. sarah has 3 friends. she wants to give each friend 4 cookies. she needs to make 12 cookies.

Explanation:

Step1: Analizar el modelo visual

El modelo muestra 3 círculos, cada uno con 4 galletas (o objetos). Entonces, el total de galletas es \( 3 \times 4 = 12 \).

Step2: Evaluar cada opción

• Opción a: 4 amigos, 3 galletas cada uno: \( 4 \times 3 = 12 \), pero el modelo tiene 3 grupos de 4, no 4 grupos de 3. Incorrecto.
• Opción b: 12 amigos, 4 galletas: \( 12 \times 4 = 48 \), no coincide con el modelo. Incorrecto.
• Opción c: 4 amigos, 4 galletas: \( 4 \times 4 = 16 \), no coincide. Incorrecto.
• Opción d: 3 amigos, 4 galletas cada uno: \( 3 \times 4 = 12 \), coincide con el modelo (3 grupos de 4). Correcto.

Answer:

d. Sarah has 3 friends. She wants to give each friend 4 cookies. She needs to make 12 cookies.
