Let x represent the quantity of child tickets sold and y represent the quantity of adult tickets sold
Child (x): $45 each
Adult (y): $85
Cost equation: 45x + 85y = 72000
Quantity equation: x + y = 1000
45x + 85y = 72000 → 45x + 85y = 72000
-45( x + y = 1000) → <u>-45x - 45y = -45000</u>
40y = 27000
y = 625
Quantity equation: x + y = 1000 → x + (625) = 1000 → x = 375
Answer: 375 child tickets and 625 adult tickets
44x
Choose which trig ratio to use. - Choose either sin, cos, or tan by determining which side you know and which side you are looking for. - Solve the resulting equation to find the length of the side. Step 1: Choose which trig ratio to use.
Answer: e?
Step-by-step explanation:
Explained in the pic above! Y = -8
Given
The average daily balance is $15
The daily periodic rate = 0.06%
The number of days in the cycle is 30
Find out the monthly finance charge.
To proof
Let us assume that the monthly finance charge = x
As given in the question
The average daily balance = $15
daily periodic rate = 0.06%,
First convert 0.06% in decimal form
= 0.0006
Daily finance charge = 0.0006 × 15
= 0.009
number of days in the cycle is 30
now
monthly finance charge
Than the equation becomes
x = 15 × 0.0006 × 30
x = 0.009× 30
x = $0.27
Thus the monthly finance charge is $0.27
Hence proved
