He had to put $65 bc. he had to balance his account then added $25
To add 13% vat we can multiply by (100%+13%) = 113% = 1.13
To remove 13% vat divide by 1.13
339 / 1.13 = 300 the discounted price.
The amount of discount = 400 - 300 = 100
Discount rate = 100 / 400 = 1/4 = 25%
Answer:
The third choice.
(480 - 400) / 400 * 100.
Step-by-step explanation:
(480 - 400) / 400 * 100
= 80/400 * 100
= 1/5 * 100
= 20%.
Answer:
The center is (5, -2) and the radius is 9/2
Step-by-step explanation:
The equation of a circle can be written in the form
(x-h) ^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x − 5)^2 + ( y + 2 )^2 = 81/4
(x − 5)^2 + ( y - -2 )^2 = (9/2)^2
The center is (5, -2) and the radius is 9/2
