A coat with an original price tag of $400 was marked down by 40%. You have a coupon good for an additional 25% off. What is the effective percent discount

65%=$260

Step-by-step explanation:

40%+25%=65%

65% of 400

65/100*400

=$260

the answer is 45%

Step-by-step explanation:

if the $400 coat has already been marketed down (you are left with 60% of the $400 which is 0.6 x 400 = 240).  If you then have an additional 25% discount it would mean 75% of 240 which is 0.75 x 240 = 180

the effective percent discount would be 45% because as a fraction 180/400 = 9/20 or if you change it on your calculator using the S<>D button makes 0.45 as a decimal and to make it a percentage you just times by 100 and there you have your correct percentage

answer: y=0 if that is what u r looking for
