You got 2 types of data $ and %!
Line them up accordingly and cross multiply.
16% is to $38 as
100% is to $x
X= 38•100/16= $237.5 the price before discount
<em>Acceleration (a) = 5.1 m/s</em>²
<em>Initial speed (u) = 16 km/h </em>⇒

<em>m/s </em>≈ <em>4.5m/s</em>
<em>
</em><em>Final speed (v) =118 km/h </em>⇒

<em>m/s</em> ≈ <em>32.8m/s</em>
<em>
</em>Distance(S) travel in that particular instant is carried out by 'Third equation of motion' i.e., v² = u² + 2aS
<em>So, When all quantities are in S.I. unit then,
</em>putting the values in the equation of motion,
<em /><em>As we have to carry out the distance covered,
</em><em>2</em>·<em>a</em>·<em>S = v</em>² <em>- u</em>²
<em>S = </em>

Putting values in derived equation,
⇒ <em>S = </em>

⇒ <em>S = </em>

⇒ <em>S = </em>

⇒ <em>S </em>≈ <em>103.489</em> <em>m
</em>
<em>
The total distance covered in that given condition is approx. 103.289 m.</em>
Answer:
We calculate the slop of a line.
How to find the slope:
Pick any two points on a graph
The formula of slope is 
For example we have two points that contains the coordinates (5,2) (7,4)
Inserting them to the formula would result in:

=
Our rate of change is rise 2, run 2.
Answer:
proper because the numerator is lower than the denominator
