A radio is being discounted 20%. If the sale price is $51.44, what was the original price of the radio? A. $12.86, B. 64.30, C.
$41.15, D. 65.05
2 answers:
The equation for decreasing a price by 20% is
original price x 0.8 = sale price
Here, we can fill in the sale price so
original price x 0.8 = 51.44
This can be rearranged to show:
51.44 ÷ 0.8 = original price
So the original price was $64.30
Answer = B - $64.30
The answer is B hope this helps

Answer:
5.2%.
Step-by-step explanation:
After 1 hour (60 / 100) * 700 = 420 gallons of beer have been exchanged.
So we have 420 gallons of 6% and 280 gallons of 4% after 1 hour.
So the strength at that time = (420* 6) + 280*4) / 700
= 5.2%.
