The cost of each dish is $2.50.

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 = $(\frac{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, \frac{20}{ 8} =\frac{10}{4}. Again we can divide 10 and 4 by 2, we will get,

$(\frac{10}{4}) =(\frac{5}{2} ) = $2.5

So we have got the required answer here.

Cost of each dish is $2.5.

On Friday, a fruit stand sold a total of 92 apples and oranges. On Saturday, the fruit stand sold four times the number of apple
andreev551 [17]

Option A : a+o = 92 , 4a+2o = 284 is the right answer

Step-by-step explanation:

Let o be the number of oranges sold on Friday and

a be the number of apples sold on Friday

So,

A total of 92 was sold on Friday will yield the equation

a+o = 92

On Saturday,

4 times the number of apples = 4a

2 times the number of oranges = 2o

So,

4a+2o = 284

Hence,

The system of equations is:

a+o = 92\\4a+2o = 284

Option A : a+o = 92 , 4a+2o = 284 is the right answer
