Answer:
7
Step-by-step explanation:
12b -b = 11b
11b = 77
Divide both sides by 11
b = 7
Kid tickets = 3d
D = adult tickets
448 = (3 * d) + d
448 = 4d
448/4 = 112
112 = d
3 * d = 336
There are 336 kid tickets and 112 adult tickets sold.
Because you are solving to find the total amount and you were given that the tax is 8% you’d do $999 times 0.08 and you’d get $79.92 and then you’d add $79.92 to $999 to find the total amount charge to his card and you’d get $1078.92
