If a grocery store is selling 3 oranges for $1.47 .What is the unit cost ?

 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.

my answer is$ 12

step-by-step explanation:

because 15 -2=12

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
