Mathematics

Answer:

12 < x

Step-by-step explanation:

In writing 12 less than a number x, the expression, 12 - x is wrong because "less than" is not the same thing as "minus" (-). Rather, the sign, "<" should have been used as follows:

12 < x.

Answer: Rs. 100

Step-by-step explanation:

Given the following :

Total expenditure for dance show = Rs. 25000

Profit made except expenditure = Rs. 12,000

Number of people who observed and paid for the show = 370

Amount paid per person will be :

(Total amount or revenue realized / number of observers who paid)

Total revenue realized = (total expenditure + profit made)

Total Revenue realized = Rs.(25,000 + 12,000) = Rs. 37,000

Amount paid per observer = (Rs. 37,000 / 370)

= Rs. 100
