Question

Dr.sox paid $1580 for a new computer system. She also paid 6.5% sales tax. How much was total cost?

Answer 1

$1,682.70

Explanation:

1. Convert the percent into a decimal by multiplying by 0.01: the percent in this problem is 6.5%, so when you multiply by 0.01, you get 0.065
2. Multiply the price by your new decimal: in this case, that would mean to multiply 1580 by 0.065, which gives you 102.7. Keep in mind that this is just the tax, not your final answer.
3. Add the tax you just calculated to the original price: add 102.7 to 1580 to get 1,682.7. That is your final answer.
