Question

amy and laura recorded the average gas mileage (mpg) of their vehicles each week for four weeks. what can be concluded about the relationships shown in the graph and table? amy and laura recorded the same gas mileage each week. both amy and laura increased their gas mileage in the first two weeks. amy had greater gas mileage than laura. laura had a constant gas mileage in the first four weeks of data. amys gas mileage time (weeks) lauras gas mileage time (weeks) 0 1 2 3 4 mpg 17 18 19 17 17

Explanation:

Step1: Analyze Amy's graph

Amy's gas - mileage graph shows an increase in the first two weeks and then a decrease.

Step2: Analyze Laura's table

Laura's gas - mileage values are 17, 18, 19, 17, 17. It increases from week 0 to week 2 and then changes.

Step3: Evaluate each option

• Option 1: Amy and Laura did not record the same gas - mileage each week as we can see from the graph and table.
• Option 2: Amy's graph shows an increase in the first two weeks and Laura's table also shows an increase in the first two weeks.
• Option 3: We cannot directly compare Amy and Laura's gas - mileage amounts from the given information as we don't have exact numerical values for Amy at each point.
• Option 4: Laura's gas - mileage is not constant as it changes from 17 to 18 to 19 in the first three weeks.

Answer:

Both Amy and Laura increased their gas mileage in the first two weeks.
