The phone case you want to buy is marked down 30%, and you have a 25% off coupon. you pay $42.00. can this equation be used to find the original price of the phone case? if so, what is the original price of the item? explain. (5 points) 3/4(0.7c) = 42

If you Multiply 42.00 and 0.30 because 30 percent as a decimal is 0.30 once your done you should get 12.6 then you subtract 12.6 from 42.00 you get 29.40 once you're done with that you multiply that product from 25% or 0.25 and you would get $7.35.
meaning that you're answer would be $7.35 please make brainliest
