Respuesta :
Number of toothpicks required per student = At least 9
Total number of students = 30
Number of toothpicks required for the entire class = At least 9 × 30 = At least 270
Number of toothpicks in the bag in the class storage room = 50
Additional number of toothpicks required to be bought to make sure there are enough toothpicks = 270 - 50 = 220
Hence, she needs to buy 220 toothpicks.
Answer:
[tex]50+x\geq 270[/tex]
Step-by-step explanation:
We have been given that Each student must use at least 9 toothpicks for the project. Her class has 30 students.
First of all, we will find the total number of toothpicks needed for 30 students by multiplying 30 by 9 that is [tex]30\times 9=270[/tex].
Mrs. Wendel knows that there is already a bag of 50 toothpicks in the class storage room. She plans to buy x additional toothpicks this afternoon to make sure her class will have enough.
So the total number of toothpicks that Mrs. Wendel has would be [tex]50+x[/tex].
The number of total amount of sticks Mrs. Wendel has, should be greater than or equal to 270.
[tex]50+x\geq 270[/tex]
Therefore, our required inequality would be [tex]50+x\geq 270[/tex].
