A store is having a 20% off sale. It gives an additional 10% off if the item is still above 100 dollars after the first discount. A jacket cost 149.99 will you get the second discount and if so, how many dollars will you save in total?

Question

Yes; 43.00

yes; 14.49

no

yes; 30.00

Answer 1

after first discount:
cost = .8(149.99) = 119.99
so yes, you qualify for the second discount.
cost after second discount = .9(119.99)
= 107.99

total savings = 149.99 - 107.99 = $42.00

none of the choices are correct, unless you have a typo in a)

Answer 2

149.99 * 0.8 = 119.99

119.99 * 0.9 = 107.99
