Answer:

325 adult tickets and 225 kids tickets

Step-by-step explanation:

a= # of adult tickets

c= # of kids tickets

a+c=550  (because they sold 550 total tickets)

1.50a+1.00c=712.50 (a tickets sold at 1.50 each, and c tickets sold at 1.00 each, for a total of 712.50

now simplify

1.5a+c=712.50    solve for c

c=712.50-1.5a     now plug in that value of c to the first equation

a+c=550, so a +(712.50-1.5a)=550

-0.5a+712.50=550

-0.5a=-162.50

a=325, so 325 adult tickets

nw remember a+c = 550, so 325+c=550

c=225, so 225 kids tickets
