1. greg spent $4 on 5 packs of sports cards.

a. how much did greg spend on each pack?
b. if greg spent half as much money and bought twice as many packs of cards, how much did he spend on each pack? explain your thinking.

Explanation:

Step1: Find per-feeder fraction

$\frac{1}{4}$

Step2: Find per-feeder weight

$\frac{5}{4}$

Step3: Calculate per-pack cost

$\frac{4}{5}$

Step4: Adjust cost for new scenario

$\frac{2}{10} = \frac{1}{5}$

Answer:

1. a. $\frac{1}{4}$
2. b. $\frac{5}{4}$ pounds
3. a. $\$0.80$
4. b. $\$0.20$

(Nota para el inciso 3.b.: Un diagrama de cinta consistiría en una cinta dividida en 4 partes iguales, cada una etiquetada con $\frac{5}{4}$ libras, representando la cantidad para cada comedero. Para el inciso 4.b.: Greg gastó $\$2$ en total en 10 paquetes, así que por paquete es $\frac{2}{10} = \frac{1}{5}$ dólares.)
