Question

A customer buys 1½ pounds of small nails at $0.59 per pound, 1½ pounds of medium nails at $0.69 per pound, and 2 pounds of large nails at $0.89 per pound. Tax costs an additional 6% of the total. What is the approximate total he pays for the nails with tax?

Answer 1

$3.92.

Explanation:

To calculate the total cost of nails with tax, we need to calculate the cost of each type of nail and then add them together, including the tax.

Let's calculate the cost for each type of nail:

Small nails:

Weight = 1.5 pounds

Price per pound = $0.59

Cost of small nails = Weight × Price per pound = 1.5 × $0.59 = $0.885

Medium nails:

Weight = 1.5 pounds

Price per pound = $0.69

Cost of medium nails = Weight × Price per pound = 1.5 × $0.69 = $1.035

Large nails:

Weight = 2 pounds

Price per pound = $0.89

Cost of large nails = Weight × Price per pound = 2 × $0.89 = $1.78

Now, let's calculate the subtotal before tax by adding up the costs of the nails:

Subtotal = Cost of small nails + Cost of medium nails + Cost of large nails

Subtotal = $0.885 + $1.035 + $1.78 = $3.7

To calculate the tax, we need to find 6% of the subtotal:

Tax = 6% of Subtotal = 0.06 × $3.7 = $0.222

Finally, we can calculate the total cost by adding the subtotal and the tax:

Total cost = Subtotal + Tax = $3.7 + $0.222 = $3.922

Therefore, the approximate total cost the customer pays for the nails with tax is approximately $3.92.

Hope this helps ^^
