First, divide the number of produce your buying buy the cost.
Box of light bulbs = 4
cost of 4 light bulbs = 3.79
Cost for item individually ( Unit rate for each item ) =x
The variable ( letter that represents a number ) is being multiplied by 4
4x= 3.79 Do the reciprocal ( the reverse ) for 4 times X to 4 divide 3.79
4/4x = 3.79/4 The 4 moves to the other side and is now dividing by 3.79
The fraction symbol also represents dividing
x = 3.79/4 Now divide the cost by four
x= .9475 round up to nearest cent .95 C
The rest do the same and 5 use the answer for $19.50 divided by 3 to complete the table by multiplying the answer of $19.50 divided by 3 to hours worked.
