Answer: 0.49 dollars, which is equivalent to 49 cents
==========================================================
Work Shown:
Divide the total cost over the number of items to get the unit cost
unit cost = (total cost)/(number of items)
unit cost = (1.47)/(3)
unit cost = 0.49 dollars
unit cost = 49 cents
---------------------------
Another approach:
3 oranges = 1.47 dollars
3/3 oranges = 1.47/3 dollars
1 orange = 0.49 dollars
1 orange = 49 cents
The unit cost is the cost of 1 item, so the the unit cost is 49 cents per orange.
Final answer:
The unit cost of an orange in this case is calculated by dividing the total cost ($1.47) by the number of units (3), which gives us a unit cost of approximately $0.49.
Explanation:
The unit price can be calculated by taking the total price and dividing it by the number of units. In this case, the total price is $1.47 and there are 3 oranges. So the unit price would be calculated as follows:
$$1.47 divided by 3 = $0.49 (rounded to the nearest cent)
Therefore, the unit cost of an orange is approximately $0.49..

if 3xa=3 times a then
so the quantity (3xa+6) is divided by 3 so factor out the three and get3(a+2) divide by three and get (a+2)+18 and the associative propertyof addition allows us to move the parenthasees to (a+2+18)=50 or a+20=50 subtract 20 from both sides and get
a=30
or (3a+6)/3+18=50
3(a+2)/3+18=50
a+2+18=50
a+20=50
a=30

The sign of the quotient of two integers depends on the signs of the integers being divided.
Both integers are positive: When both integers are positive, the quotient will also be positive. This is because dividing positive numbers will always result in a positive value.
For example, if we divide 8 by 2, the quotient is 4
Positive divided by negative: When a positive integer is divided by a negative integer, the quotient will be negative. This is because dividing a positive number by a negative number results in a negative value.
For example, if we divide 10 by -2, the quotient is -5
In summary, the sign of the quotient of two integers depends on the signs of the integers being divided. If both integers are positive, the quotient will be positive. If a positive integer is divided by a negative integer, the quotient will be negative.
