Question

A set of 8 dessert dishes cost $20. what was the cost of each dish

Answer 1

$20 / 8 dessert dishes = $2.50

The cost of each dish is $2.50.

Answer 2

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 = $
`((20)/(8))`

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,
`(20)/( 8) =(10)/(4)`. Again we can divide 10 and 4 by 2, we will get,

$
`((10)/(4)) =((5)/(2) )` = $2.5

So we have got the required answer here.

Cost of each dish is $2.5.
