The local middle school had a concert to raise money. tickets were $6.00 for adults and $4.00 for children. the committee figured there were 480 in attendance and that $2,340.00 was raised. how many adults and how many children attended?

Respuesta :

A) 6A + 4C = 2,340
B) A + C = 480 Multiplying equation B by -4
B) -4A -4C = -1,920 then adding equation A
A) 6A + 4C = 2,340

2A = 420
Adults = 210

B) A + C = 480
Children = 480 -210
Children = 270
