x = ±6
Hey there! I'm happy to help!
The unit rate is how much stuff there is per 1 unit. All ratios can be rewritten as fractions, this one could be 0.2/0.5. The word per means divide, and fractions are basically dividing. So, we want the denominator to be 1.
To get 0.5 to 1, we multiply by 2. So, we will multiply the fraction by 2/2.
0.2/0.5(2/2)=0.4/1
Therefore, the unit rate is 0.4/1 or 0.4:1 or 0.4 per 1.
Have a wonderful day! :D

Based on the calculations, the number of books that were bought by Hugh are 4 books.
<h3>How to calculate the number of books?</h3>
In order to determine the number of books that were bought by Hugh, we would substitute the value of the number of magazines into the given equation and then evaluate as follows:
3.95m + 8.95b = 47.65
3.95(3) + 8.95b = 47.65
11.85 + 8.95b = 47.65
8.95b = 47.65 - 11.85
8.95b = 35.8
b = 35.8/8.95
b = 4.
In conclusion, the number of books that were bought by Hugh are 4 books.
