Bill pays $49 for an item after it has been discounted 30%. What was the original price of the item?
makvit [3.9K]
If an item has been discounted 30%, then it is currently worth 70% of the original price. This tells us that $49 is 70% of the original price. Therefore, you need to divide $49 by 70% to get your answer (you have to work backwards; remember that you would have multiplied the original number by 0.7 to get 49):
49÷(70/100)= $70
Therefore, the price of the original product was $70

Answer:

  26. B(t) = 500·1.075^t; B(6) ≈ $772

  27. G(t) = 70·0.72^t; G(3) ≈ 26 g

Step-by-step explanation:

The equation with the plus sign is used when the value is increasing. The minus sign is used when the value is decreasing. The 'a' in each equation is the initial value.

__

26. B(t) = 500·1.075^t

  B(6) = 771.65

The balance after 6 years is about $772.

__

27. G(t) = 70·0.72^t

  G(3) = 26.127

About 26 grams are left after 3 days.
