A local charity sells total of 480 tickets to golf tournament fundraiser. A member ticket costs $50. A non-member ticket costs $65. How many non-member tickets were sold if the total ticket sales are / $24.065

Non-member tickets sold rounding off to whole number = 4

Step-by-step explanation:

Given dа ta:

Total tickets sold = 480

Member ticket cost = 50

Non - member ticket cost = 65

Total tickets sales = 24 065

Let count of member ticket sold = x

Let count of non-member ticket sold = y

x + y = 480 (equation 1)

50x + 65y = 24065 (equation 2)

From equation 1 x = 480 - y (equation 3)

Substituting equation 3 into equation 2

50 (480-y) + 65y = 24065

24000 - 50y + 65y = 24065

-50y + 65y = 24065-24000

15y = 65

y = 4.33 (to 2 decimal place)

Non-member tickets sold rounding off to whole number = 4
