Answer:
question 4 is x=6 so i believe it is true and
question 5 is false
Step-by-step explanation:
Ok so x is the original price and we want to solve if the original price was 48 so x=48. When we substitute this into the equation we get 0.75(48)-0.15(0.75x48). When we simplify this expression we get 30.6. The current price is $30.60. Hope this helps.
