Keep in mind that a system of linear equations will consist of two equations using the same variables and the variables will represent the same thing for both equations, i.e., if you use X as a variable in the first equation and X represents a number of Beers then you need to use X in the second equation and it needs to represent number of Beers in the second equation. 1. A cab company charges a $3 boarding rate in addition to its meter which is $2 for every mile. Answer: A cab company charges a $3 boarding rate in addition to its meter which is $2 for every mile.

Add 2 to x to get 5 Adding 2 to x to get 5 means that whatever x is, when I add 2 to x, it has to equal to 5 The equation is: 2 + x = 5 3. My daughter wants to start new business selling lemonade. The cost for supplies totaled $15.82. She plans to sell each glass of lemonade for $0.35. a. Linear Equation will be: y= . 35x- 15.82 b. How much money will she make if she sells 30 glasses of lemonade? She will lose $5.32 c. How many glasses of lemonade will she need to sell to break even? She will need to sell 46 glasses to break even d. How many glasses of lemonade must she sell to make $10.00? she will need to sell 74 to make $10.00 e. If my daughter sells an average of 20 glasses of lemonade a day, how many days will it take her to make $25.00? if she sells an average of 20 glasses of lemonade per day to make $25 it will take her 6 days....
