While Christine was visiting her sister in ashland she bought a microscope that was marked down 60% from the original price of 75$. If the sales tax in Ashland is 10% what was the total cost of the microscope?

The total cost of the microscope=$37.50

Step-by-step explanation:

Step 1: Get the discount amount

Discount amount=Discount rate*original price

where;

original price=$75

discount rate=60%

replacing;

Discount amount = (60/100) * 75=45

Discount amount=$45

Step 2: Calculate sale price

The sale price can be calculated as;

sale price=Original price-discount amount

where;

discount=$45

original price=$75

replacing;

Sale price = (75-45) = $30

Step 3: Calculate tax amount

Tax=10% of original price = (10/100) * 75=7.5

Step 4: Total cost of microscope

Total cost=sale price+tax

where;

sale price=30

tax=7.50

replacing;

Total cost = (30+7.50) = 37.50

The total cost of the microscope=$37.50
