you would first have to multiply 20% by 3.24 and then youll get 0.648 then you subtract 3.24 by 0.648 and get 2.60. Then multiply 20% by 3.99 and get 0.798 then subtract 3.99 by 0.798 and get 3.19 then add 2.60 with 3.19 to get 5.79. 5.79 is how much she spent with 20% off

90% of a number is x . What is 100% of the number? Assume x>0

mariarad [96]

Step-by-step explanation:

Let the required number be n

$\therefore \: \frac{90}{100} \times n = x \\ \\ \therefore \: \frac{9}{10} \\ \\ \therefore \:n = \frac{10}{9} x \\ \\ \therefore 100\% \: of\:n = \frac{10}{9} x \times 100\% \\ \\ = \frac{10}{9} x \times \frac{100}{100} \\ \\ = \frac{10}{9} x \\$

NOTE: A number is always 100% in itself.
