Caleb spent 34.95 on 5 pounds of coffee. how much was the coffee per pound?
horsena [70]
It would be $6.99. All you have to do is divide the total (34.95) by pounds of coffee (5). 34.95 / 5 will give you 6.99! You can check this by doing 6.99 * 5, which would again give you 34.95. Contact me if you need any more help. :^)

A book sold 39,300 copies in its first month of release. Suppose this represents 6.1% of the number of copies sold to date. How
alexdok [17]

Answer:

644,262 copies

Step-by-step explanation:

Since this is a proportion problem, and we are given three values and one variable which is the total number of copies sold to date (x). Then we can use the Rule of Three to solve this problem. To do this we simply multiply the diagonal values and divide by the last value which would give us the value of the variable x

39,300 copies  <======>  6.1%

    x   copies   <=======>  100%

(100*39,300) / 6.1 = 644,262 copies

Therefore, a total of 644,262 copies have been sold to date.
