Answer:
y = $28.75x
Step-by-step explanation:
Given that,
Tickets to a carnival cost $28.75 each.
We need to find y i.e. the cost of x tickets.
When the number of tickets are x, to find the cost of x tickets, we must find it by multiplying 28.75 and x i.e.
y = 28.75x
Hence, the cost of x tickets is equal to $28.75x.
Answer:
Step-by-step explanation:
The exponential growth equation that represents the rabbit population y) after x years is y = 500(1.25)ˣ
Exponential growth is given by:
y = abˣ
where a is the initial value of y, b is the multiplier and b>1, y, x are variables.
Let y represent the total rabbit population after x years.
Since there were 500, introduced hence a = 500. Also the population increases 25% each year, hence:
b = 100% + 25% = 1 + 0.25 = 1.25
y = 500(1.25)ˣ
The exponential growth equation becomes y = 500(1.25)ˣ
The first one should be $178
The second one would be 8 quarters
His current balance is $321.34
She would have $110.00 but with penalty she would have $106.75
