Debbie Redden has a 25%-off coupon and is purchasing a 2.5 gallon can of primer sealer paint that has a regular price
of $39.99.
a. What is the markdown?
b. What is the sale price?
c. What is the sale price using the percent paid method?

A) the markdown is $9.99
b) original sale price is $39.99
c) after using the coupon the price would be $29.99

in order to find this out you would first divide the original price of 39.99 by 100 in order to find out what 1% is. Then you would multiply this number by 25 to find out what 25% is. Then you would subtract the original amount of 39.99 by the 25% amount in order to find out how much is taken off

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.
