Alocal sports team sells 6 tickets for $3,8 tickets for $4,and 10 tickets for $5.write a rule and equation to find out the cost of 20 tickets.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
