Candy selling at $6.00 per pound will be mixed with candy selling at $9.00 per pound. how many pounds of the more expensive candy are needed to produce a 15-pound mixture that sells for $7.00 per pound? a. 5 b. 6 c. 9 d. 10

x+y=15 the total of 15 pounds

(6x+9y)/15=7 the average of each pound out of 15 that is valued $7

(6x+9*(15-x))/15=7

(6x+135-9x)/15=7

(135-3x)/15=7

135-3x=7*15

135-3x=105

-3x=-30

x=10

deduce that y=15-10=5

so basically, you can conclude that 10 of the 1st candies are valued at 60$ and 5 pound of the second will be valued at at $45 which adds up to $105

and 105/15=7 which shows us that we were right and overall 15 pounds has and average pound value of $7

hope this : )

105/15=7 which means that overall 15   pounds do have an average per-pound value of 7
