Answer:
170 tickets.
Step-by-step explanation:
Write formulas for the question.
Then use substitution.
So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.
Step-by-step explanation:
Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
Answer:
y=45000(1-0.03)^x
Step-by-step explanation:
1) the exponential decay formula is
y=c(1-r)^x
where c= starting amount
r=rate of change
x=time
so
y=45000(1-0.03)^x
y=45000-1350x
