Answer:
A
Step-by-step explanation:
I've forgotten the exponent rules for exponent operations, but one way to do this is to find the value of the expression given (2^-5 * 2^7)^-3 (which is equal to 0.015625) using a calculator, then use your calculator to find which answer choice is equal to the expression given AKA 0.015625. I did this and got A, but you should probably still look up exponent rules for future reference. Trust me, this question is actually WAY easier than what it probably looks like to you, as long as you know the exponent rules. :)
Give me Brainliest and have a great day! :)

The total cost is $43.5 and it is obtained from the equation c = 6.5n + 25
<u>Solution:</u>
Given that, while your family is visiting Deep creek lake, you and your mother decide to go boating.
The Rangers charge $6.50 per hour in addition to $25.00 deposit to rent a canoe.
If you wish to rent the canoe from 12:30 to 3:30 PM,
We have to write and solve a linear equation to find the total cost to rent the canoe.
Now, we know that,
<em>total cost = charges + rent fee
</em>

Let total cost be "c" and number of hours rented be "n"

Now, they used canoe from 12:30 to 3:30, which means 3 hours of time
So, put n = 3 in (1)
c = 6.5(3) + 25
c = 19.5 + 25
c = 43.5
Hence, the total cost is $43.5 and it is obtained from the equation c = 6.5n + 25
When solving an inequality, the rules are similar to solving an equation, but instead there's an inequality sign. The only thing to be careful about when solving an inequality is that when you multiply/divide by a negative number, you have to flip the inequality sign, but you don't have to worry about that here!
So you have 2x < 8.
Divide both sides by 2 to isolate the variable, x:
Your final inequality is x < 4.
