Chocolates costing $8 per pound are to be mixed with chocolates costing $3 per pound to make a 20 lbs mixture. If the mixture is to sell for $5 per pound, how many pounds of each chocolate should be used? Which of the following equations could be used to solve the problem?

8x + 3(20) = 5(x + 20)
8x + 3(20 - x) = 5(20)
8x + 3x = 5(20)

The answer will be B.

I had this question before and got it right.

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
