1739 Reference Books Sold.

Step-by-step explanation:

Do this problem, we have to convert 34% to a decimal by taking the whole number value of the percent then dividing by 100. This gives us 0.34.

We can then take 4700 and multiply it by 0.34 and get 1739.

This also means that 0.66 is left over to be sold that hasn't sold in the month,

Take .66 and multiply it by 4700 to get 3102.

As long as 3102+1739=4700 is true, this means we have accounted for all values in the pie chart. At this point, we know from this that 1739 is the number of reference books sold out of the 4700.

over the argument its not good to fight.
