$733.29. Simply because you take $896•0.12 to find the 12% off and then you take that subtracted by the starting total. After you get the 12% off then you multiply that number by .07 to get the sales tax. After you find that then you add the number you got after multiplying to the number you got after taking off the 12%.

Nina took an exam. When her results came, she had 40% correct and 68% incorrect. Find the percent to correct answers to incorrec
vivado [14]

Answer: She had 27.2% correct.

Step-by-step explanation: To find the percent, we can divide the part and whole then multiply the quotient by 100. After that we'll need to convert the percent to a decimal. In mathematical terms, the formula will be,

\frac{part}{whole}=quotient*100

40% will be the part and 68% will be the whole.

<u><em>Step 1.</em></u>

Convert 40 into a decimal by dividing it by 100.

40 ÷ 100 = 0.4

<u><em>Step 2.</em></u>

Multiply 0.4 by 68.

0.4 × 68 = 27.2

Hence, she had 27.2% correct.
