PLS POS PS, OKS PLS PLS PLS PLS I NEED HELP IF I DINT GET HELP IM GONNA FAIL MATH AND THEN IM GONNA BE SAD During a sale, a store offered a 15% discount on a couch that originally sold for $780. After the sale, the discounted price of the couch was marked
up by 15%. To the nearest whole number, what percent of the original price was the price after markup?

This is based on how I understood the question, is 98%.

Step-by-step explanation:

15% = 0.15

0.15*780=117

780-117=663

Price after discount: $663

663*0.15=99.45

663+99.45=762.45

After rounding to nearest whole number: $762

762 of 780 is 98%.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
