One evening 1500 concert tickets were sold. tickets cost $20 for pavillion seats and $15 for lawn seats. total receipts were $27,500. how many tickets of each type were sold?

500 lawn seats were sold and 1,000 pavillion seats were sold

Step-by-step explanation:

15 (cost of lawn seat) x 500 (amount sold) = 7500

20 (cost of pavillion seat) x 1,000 (amount sold) = 20,000

7,500 + 20,000 = 27, 500 (total receipts)

10 miles

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
