A text messaging plan for a cell phone w/unlimited messages for $5/per month or a plan that charges $2 for the first 30 messages and then 10 cents for each additional message. How many messages (above the initial 30) would you need to send or recieve to make buying the unlimited messages plan a better deal?

You can put this solution on YOUR website!
Let amount of nuts be "x".
Value of nuts is 8x dollars
Value of pretzels is 3(50) dollars
EQUATION:
Value of nuts + Value of pretzels = value of mixture
8x+150=6(x+50)
8x+150=6x+300
2x = 150
x= 75 lbs. of nuts should be added to the pretzels
