The school production of 'our town' was a big success. for opening night, 501 tickets were sold. students paid $3.00 each, while non-students paid $5.00 each. if a total of $ 1767.00 was collected, how many students and how many non-students attended?

no of students are 369

and no of non students are 132

Explanation:

given data

ticket sold  = 501

student paid = $3

non students paid = $5

total collection = $ 1767

to find out

how many students and how many non-students attended

solution

we consider here no of students  = x

and no of  non students = y

so we can say that

x + y = 501   1

y = 501 - x     2

and paid by students then equation will be

3x + 5y = 1767   3

put value 2 equation in equation 3

3x + 5(501 - x) = 1767

3x + 2505 - 5x = 1767

-2x + 2505 = 1767

x = 369

so y will be y = 501 - 369

y = 132

so no of students is 369

and no of non students is 132

a manufacturer of printed circuit boards uses exponential smoothing with trend to forecast monthly demand of its product. at the end of december, the company wishes to forecast sales for january. the estimate of trend through november has been 200 additional boards sold per month. average sales have been around 1000 units per month. the demand for december was 1100 units. the company uses α = 0.20 and β = 0.10. make a forecast including trend for the month of january.

i'ts proportional. if the inflation rate is 12% for example, the cpi will be 12% less.

hope it ,
