Question

Three friends go grocery shopping together and buy strawberries. Akio buys 2 pounds (lb) for $1.50, Gordon buys 3 pounds for $2.25, and Maria buys 4 pounds for $3.00.

Identify the graph and unit price that represent the strawberry costs.
a. Graph: Cost (dollars) vs. Pounds (lb), Unit Price: $1.50
b. Graph: Cost (dollars) vs. Pounds (lb), Unit Price: $2.25
c. Graph: Cost (dollars) vs. Pounds (lb), Unit Price: $3.00
d. Graph: Pounds (lb) vs. Cost (dollars), Unit Price: $1.50

Answer 1

All three friends, Akio, Gordon, and Maria, pay a unit price of $0.75 per pound for strawberries. The correct representation is a graph showing Cost (dollars) versus Pounds (lb), depicting a consistent unit price.

Step-by-step explanation:

The question involves identifying the correct graph and calculating the unit price of strawberries bought by each friend. To find the unit price, we divide the cost by the number of pounds purchased. For Akio, the unit price is $1.50/2 lb = $0.75/lb. Gordon's unit price is $2.25/3 lb = $0.75/lb, and Maria's unit price is $3.00/4 lb = $0.75/lb. All three friends are paying the same unit price for strawberries, which is $0.75 per pound.

As for the graph, it should depict the Cost (dollars) vs. Pounds (lb), showing how the cost increases with the number of pounds bought. The correct graph will have a straight line illustrating the consistent unit price among the three friends as the quantity of their purchase increases.

Therefore, the correct graph and unit price for this situation are:

• Graph: Cost (dollars) vs. Pounds (lb)
• Unit Price: $0.75
