<h3>What is an equation and its solution?</h3>
When two expressions are connected with the equals sign (=) in a math equation, it expresses the equality of the two expressions. A number that may be entered for the variable to produce a true number statement is the solution to an equation.
Let the hours Amelia need to work=h
Amalia paid=$20
Payment of each hour=$2.50
So, we can make an equation with given problem
40=20+2.50h
40-20=2.5h
20=2.5h
h= 8
So, Amelia need to work for 8 hours to get $40.

Answer: £165.41
Step-by-step explanation:
Price of bike when purchased in 2010 = £300
Depreciation rate yearly = 18%
Value of bike in 2011
Purchased price - depreciation value
= £300 - £300 * 0.18
= £300 - £54
= £246
Value of bike in 2012
= 2011 Price - depreciation value
= £246 - £246 * 0.18
= £246 - £44.28
= £201.72
Value of Bike in 2013
= price of 2012 - depreciation value
= £201.72 - £201.72 * 0.18
= £201.72 - £36.31
= £165.41
Price in 2014 would be £165.41
