A:
Answer:-2.75 x = -233.75 / -2.75 x = 85.00 plug value of x in (1) 1.00 x + 1.00 y = 150.00 85.00 + y = 150.00 y = 150.00 -85.00
y = 65.00 y = 65.00 x= 85 number of child tickets y= 65 number of adult ticketsStep-by-step explanation:x= number of child tickets y= number of adult tickets Total sold 1.00 x + 1.00 y = 150.00 .............1 Total value 4.75 x + 7.50 y = 891.25 .............2 Eliminate y multiply (1)by -7.50 Multiply (2) by 1.00 -7.50 x -7.50 y = -1125.00 4.75 x + 7.50 y = 891.25
