Multiply: $500 * 0.06 = tax
Add the tax to the cost of the item to find the total cost.
tx= 30
total cost = 530
Thanks, How do i find the percent notation of a fraction?
14 over 25
Divide: 14 by 25.
Then multiply by 100 because percent means the number out of 100.
Or you can just move the decimal point two places to the right to get the percentage.
56% thanks
How do I solve for N?
2/10 = n/15
You could set this up as a proportion and cross multiply.
2/10 = n/15
2*15 = 10n
30 = 10n
3 = n
SO the answear would be 2/10 = 30/15
because 2*15= 30
Bryan -- I showed you how to solve this problem.
2/10 = n/15
2*15 = 10n
30 = 10n <<Divide both sides of the equation by 10.
3 = n
