Given, the cost of a set of 8 dessert dishes = $20.
To find the cost of each dish we have to divide here, as the number of dishes is decreasing.
So the cost of 1 dessert dish = $[tex] (\frac{20}{8}) [/tex]
To simplify it we will divide the numerator and denominator by a common factor of it. Here the common factor of 20 and 8 is 2. By dividing them by 2 we will get, [tex] \frac{20}{ 8} =\frac{10}{4} [/tex]. Again we can divide 10 and 4 by 2, we will get,
$[tex] (\frac{10}{4}) =(\frac{5}{2} ) [/tex] = $2.5
So we have got the required answer here.
Cost of each dish is $2.5.
