Tomorrow, mrs. wendel's class will be using toothpicks for a science project.  each student must use at least 9 toothpicks for the project.  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. if her class has  30 students, which number sentence represents this situation?

1)  Each student must use at least 9 toothpicks for the project and her class has 30 students, so

at least 9*30 toothpicks are needed.

2)  Mrs. Wendel has already 50 toothpicks,

so she needs to buy at least (9*30 - 50).

x ≥ 9*30 - 50

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

goog may be able to you find that answer
