Answer:
Now, each student contributes= Rs 61 1/2= Rs 123/2 ( mixed fraction ).
Therefore, total no. of students=Rs (1953/2÷123/2) = 15.87
Rounding off 15.87 to 16.
There were 16 students
(i hope it is correct answer. pls mark as brainliest)
Answer:
Adult= $24
child= $21
Step-by-step explanation:
first let's create an equation for each one.
Day 1: 7x+8y=168
day 2: 14x+13y=294
By doing so we can either graph and get the points for x,y or we can substitute each (x=0) (y=0) and solve manually.
x-int.= (24,0)
y-int.=(0,21)
Answer: D
Step-by-step explanation:
Answer:
A(n) = 5.1×n + 4.5
Step-by-step explanation:
A(n) = A(n-1) + 5.1
A(1) = 9.6
A(n) - A(n-1) = 5.1 ,where n ≥ 1
This means that (A(n)) is an arithmetic sequence where :
<u>The common difference</u> r = 5.1
and
<u>The first term</u> A(1) = 9.6
Therefore
A(n) = A(1) + (n - 1)×r
= 9.6 + (n - 1)×5.1
= 9.6 + 5.1×n - 5.1
= 5.1×n + (9.6 - 5.1)
= 5.1×n + 4.5
