Answer:
A. Equation is 
B. Cost is $88
Step-by-step explanation:
A)
Suppose you rent for x hours and each hour costs $15.75
<u><em>How much would you need to pay?</em></u>

Moreover, there is a $25 dollar (fixed) deposit for renting, so that gets added to your payment. All in all, you have to pay 
This is the equation of renting a snowboard for x hours.
Equation is 
- Where x is the number of hours you rent the snowboard, and
- c is the total cost
B)
If you are renting from 8.30 to 12.30, you are basically renting for 4 hours.
To know how much it will cost, you simply plug in 4 into x (in the equation):

Cost is $88
Answer:
The result is 60
Step-by-step explanation:
We have to use this expression showing BODMAS rule. According to the rule, we must first solve the brackets. In our expression, the term within the bracket is (12-4) squared = (8) squared = 64.
Then we need to perform the addition followed by subtraction.
The expression becomes:
11 squared - 64 + 3
= 121 - 64 + 3
= 124 - 64
= 60
So, the result of the expression is 60.
