In 1987 a recording artist sold 14,000 albums. in 1998 that same artist sold 4,683 albums. find the rate of change in record sales from 1987 to 1998. a. 1/847 years per album. b. –847 albums per year. c. 847 albums per year. d. –847 years per album.

The rate of change in the record sales is the difference of the number of albums sold over the time elapsed from 1998 to 1987. That is,
                          rate of change = (4683 - 14000) / (1998 - 1987) = -847
Thus, the answer is letter B. 

78 laundries

$0.25

Step-by-step explanation:

If the box contains 195 scoops and at once he uses 2 1/2 you have to divide 195 by 2 1/2 and you get 78.

How much is he paying for each load? you have to find the unit rate. The box costs $19.99 he can do 78 laundries at once so you divide the money by the quantity or in other words $19.99 by 78 and get 0.2562820512820513, since we are talking about money we use only the firs two decimals, so he pays $0.25 per load of laundry.
