= x= 14
The cost price of the table is $40.
<h3>What is Gain ?</h3>
Gain is the amount gain by selling the product at a higher price than its cost.
Let the cost of the table is $ x
The percentage gain is x% (as given in the question)
Cost price = ?
It is known that
Step 1 : Gain = ( selling Price - Cost Price) * 100 / Cost Price
Selling price = 56
Cost Price = $ x
Therefore substituting the value
x = (56 - x) * 100 / x
x² = 5600 - 100x
x² +100x -5600 = 0
Step 2 : Factorizing
x² + 140x - 40 x -5600 = 0
x( x+14 ) -40( x +14) = 0
( x - 40)(x +14) = 0
x = $40
Therefore the cost price of the table is $40.

Answer:
d = 10s
Step-by-step explanation:
The formula for calculating the speed of Sumi is expressed as;
Speed = distance/time
Given
Speed = 10ft/s
time = s seconds
Required
Distance travelled as a function of time;
from the formula;
Distance = Speed * time
Distance = 10 * s
d = 10s
Hence the equation that expresses the distance d that sumi has traveled as a function of the time s in seconds since she started riding her bike is;
d = 10s
