This question is incomplete. Here is the complete question:
The cost of a phone is reduced by 20%. The new cost is $70.40 . What was the original price?
1. $88.00
2.$84.00
3.$58.40
4.$56.00
Answer:
The correct answer is option 1. $ 88.
Explanation:
Let's analyze the information we have:
We know that the cost of the product was reduced by 20%, leaving $ 70.4 as the final price.
As we do not know what the original cost of the product is, we will assign an x.
Now, we know that 20% is the reduced cost, so we can logically say that what is left represents the remaining 80%, that is, the $ 70.40.
So, now we will do a cross-multiplication:
If 80% ---- 70.40
100% --- x
80x = 70.40. 100
80x = 7040
X = 7040: 80
X = 88
This way we can verify that the correct option is $ 88
