Answers
Answer:
Refer the attached graph.
Step-by-step explanation:
Given : Yolanda participated in a walkabout in which each kilometer walked raised $10 for charity.
Her goal was to raise more than $300 on Saturday and Sunday. She raise $50 on Saturday.
To find : Which graph shows all the distances, in kilometers, that Yolanda could have walked on Sunday to reach her goal?
Solution :
Let she walked x km on Sunday,
Since, The money she earns per km = $ 10
Hence, the total money she earn on Sunday = 10 x
While, the money she earned on Saturday = $ 50
Thus, the total money she earn on both Sunday and Saturday = 50 + 10x
According to the question,
50 + 10 x > 300
Which is the required inequality that shows the given situation.
For graphing the above inequality,
The related equation of the above inequality is 50 + 10 x = 300 ⇒ 10 x = 250 ⇒ x = 25
Which is the line, parallel to y-axis.
Since, at origin , 50 + 10 × 0 > 300 ( False )
Thus, the inequality will not contain the origin,
Also, > sign shows the doted line.
Refer the attached graph below.
