A snowboard was $180 but marked as 30% off. There is a state tax of 7.5%. How much would you pay for the snowboard

Answers

Answer:

180(.30)=54, 180-54=126, 126(0.075)=9.45+126=135.45

Step-by-step explanation:

The total is $135.45.

Answer:$135.45

Step-by-step explanation:

The four fundamental operations of arithmetic are addition, subtracting, multiplying, and dividing two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the data given in the question,
