Option B - ($) Cost per Day
(15, 60), (10, 40), (5, 20), (0, 0)
Two options for passes to ride public transportation are displayed in the graphs. Is Option A or Option B the better buy? Choose 1 for Option A and 2 for Option B.
__ is the better buy.

Answer 1

To determine which option is the better buy, we can compare the cost per ride for both options at the same number of rides.

Let's analyze the costs based on the coordinates given:

Option A:

• 21 rides for $63: Cost per ride = $63/21 = $3
• 14 rides for $42: Cost per ride = $42/14 = $3
• 7 rides for $21: Cost per ride = $21/7 = $3
• 0 rides for $0: Cost per ride = $0/0 = $0 (not applicable)

Option B:

• 15 rides for $60: Cost per ride = $60/15 = $4
• 10 rides for $40: Cost per ride = $40/10 = $4
• 5 rides for $20: Cost per ride = $20/5 = $4
• 0 rides for $0: Cost per ride = $0/0 = $0 (not applicable)

Comparing the costs per ride:

• Option A: $3 per ride
• Option B: $4 per ride

Since Option A has a lower cost per ride than Option B, Option A is the better buy.

So the answer is: 1 is the better buy.
