THe total ticket sales for the basketball game were $1,625.00. Adult tickets were $7.00, and student tickets were $3.00. Twice as many students bought tickets as adults. How many student and adult tickets were sold?
S = 2A
7A + 3S = 1625
Substitute 2A for S in second equation and solve for S. Insert that value into the first equation and solve for A. Check by inserting both values into the second equation.
