Answer:
what was paid exactly per student as entrance fee is $6.25
Step-by-step explanation:
In this question, we are told that some kids went to an excursion with their teachers and paid a certain total bill. we now need to know the amount paid per child as the entrance fee to the zoo.
Firstly, we need to subtract the amount paid by the teachers so we know exactly how much was spent on the students entrance fee alone.
subtracting the $5 from the total we have $530 - $5 = $525
Now to know what was paid as entrance fee per student, we simply divide this by the total number of students. That will be 525/84 = $6.25
This means that what was paid exactly per student as entrance fee is $6.25
Answer:
3x + 7 + 2x -1
Step-by-step explanation:
(3x+2x)+(7-1)
5x + 6
6 / 5
x=1.2 or 2/10
I found the awnser by doing 10x10x2 witch equals 200. Then i know that 10x9 equals 90 so, you would get 29 dimes.
This is a decay problem,
The equation is written as start value x (1 - rate)^tike
Using the information given in the problem:
a) Total = 120(1-0.12)^Hours
b) Replace hours with 19 and solve:
Total = 120(1-0.12)^19
Total = 120(0.88)^19
Total = 10.57674 mg
Round the answer as needed.
