If the relationship between the number of tickets sold and the number of hours proportional ? If so, how many tickets were sold in 8 hours ?

t = 640

Step-by-step explanation:

tickets are directly proportional to number of hours.

t =kh

we find K.

240 = 3k

we divide by 3 in both sides.

k = 80

we substitute K to find how many tickets.

t =80 × 8

t = 640

it doesn't matter if you chose any two, e.g., you would get the same answer even if you used 5 and 400, or 9 and 720
