Sometimes a diagram can be helpful. If x is the distance from the house to the parallel side of the fenced plot, then the total length of fence will be x + x + 30 (feet). Jane wants to find x such that this length is 100 (feet).
The appropriate equation is ...
... A. x + x + 30 = 100
Solution: We are given:
Sales tax
The pre-tax price of the supplies
We have to find the total cost of the supplies.

Therefore, the total cost of the supplies = pre-tax price of the sales + sales tax amount
=$48 + $3.36
=$51.36
