a = your total price before the coupon and sales tax.
b = your coupon's given discount (for example, 25% off)
c = your discounted total
(a - (ab)) = c
c + (.075c) = your answer.
With some numbers plugged in:
a = 50$, b = -25%
50 - (50 x .25)
50 - 12.5 = 37.50$
37.5 + (37.5 x .075)
37.5 + 2.82* = 40.32$
So you would have to pay $40.32
The proportion of students that got the recommended amount of sleep is 0.179.
<h3>What is a proportion?</h3>
A proportion can be defined as an expression which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.
<h3>How to calculate proportion of students that got the recommended amount of sleep?</h3>
Since the total number of students in this class is 28, we would develop an expression to relate the number of students that sleep at least for 5 hours per night:
Proportion = 5/28
Proportion = 0.179.

Answer: The specific heat of this compound is
a) It is higher than the specific heat of water.
Explanation:
Specific heat is the amount of heat needed by a substance of one gram to raise it's temperature by 1°C.
This specific heat is impacted by the strength of hydrogen bonding in any substance.
Hydrogen has the highest specific heat.
Value of specific heat is directly proportional to strength of bonding in a substance.
If the bonding is strong, it will need more energy to raise its temperature. Hence, specific heat will be more for that substance.
