Answer:
The cost of each pound of jelly beans: $2.75
The cost of each pound of almonds: $3.75
Step-by-step explanation:
A = The cost of each pound of almonds
J = The cost of each pound of jelly beans
9A + 7J = 53
3A + 5J = 25
Multiply 3A + 5J = 25 by (-3)
-9A -15J = -75
Now 2 new equations:
9A + 7J = 53
-9A -15J = -75
------------------------------Add
-8J = - 22
J = 2.75
3A + 5(2.75)= 25
3A + 13.75 = 25
3A = 11.25
A = 3.75
A prime factor has no multiples and cant be broken down any further
Three hours after the bus starts out, it's 150 miles ahead of the truck. Then the truck starts out, and it gains (65-50)=15 miles on the bus every hour. If neither of them ever stops for anything, the truck will catch up to the bus in ( 150/15 ) = 10 hours. . . . (The hint is useless.)
