Answer:
2,000
Step-by-step explanation:
write out an equation that represents the problem. the original price X fell by 15% to a new price of 1700:
X - (X*15%) = 1700
X(1-0.15) =1700
X=1700/(1-0.15)
X=2,000
convert 15% to decimal form:
15%=0.15
Students = 380
Adults = 150
You can get this by using x = students and y = adults. Then set up a cost equation of:
3x + 4y = 1740
and a total tickets equation of
x + y = 530
Solve using any method.
