Add 53.46 and 3.94. Then divide it by 3.

Ok

anonymous · Answer

But the total with tax and everything is 53.46

anonymous · Answer

x=cost of a bag of dog food

We know that the cost of 3 bags + tax is the total cost, 53.46. We also know that the tax is 3.96.

3x + 3.96 = 53.46

We want to isolate x.

3x + 3.96 - 3.96 = 53.46 - 3.96
3x = 49.50
3x/3 = 49.50/3
x = 16.50

The cost is $16.50.
