Answer:

N=35

Step-by-step explanation:

Given equation is represented as:

2/7 = 10/N

Since the equation is expressed in fractional form, let us multiply both left hand side and right hand side by N:

2/7 * N = 10/N * N

=> 2N/7 = 10

Multiplying both left hand side and right hand side by 7:

2N/7*7 =10*7

=> 2N = 70

Dividing both left hand side and right hand side by 2:

2N/2 = 70/2

=> N = 70/2 = 35

Hence the required value of N is 35.

Zinaida [17]

Total tickets sold = 159
Total sales = $1100.60
Child admission = $5.20
Adult admission = $8.90

Assumed all 159 tickets are Child admission tickets
Total sales = 159 x 5.2 = $826.80

Difference in amount = $1100.60 - $826.80 = $273.80
The difference must be contributed by the Adult Admission Tickets, which has a difference of $8.90 - $5.20 = $3.70

$273.80 ÷ $3.70 = 74 adult tickets

159 - 74 = 85 child tickets

Answer:

B) 47

Step-by-step explanation:

If we assume the 2.5P is more accurately 2.54P, then we have two relations between N and P:

2.54P = 2N
N = P +10

Solving the second for P gives ...

P = N -10

and substituting that into the first gives ...

2.54(N -10) = 2N

0.54N -25.4 = 0 . . . . . . subtract 2N

N -47.037... = 0 . . . . . . .divide by 0.54

N ≈ 47 . . . . . . . . . . . . . . add 47.037... and round

The closest value of N is 47.

Comment on the problem

If you take the problem at face value, you compute N=50. The closest offered answer is still 47. In this scenario, the relationship between inches and centimeters is irrelevant, as there are no inches anywhere in the problem.
