Question 471375: Solving a Value Mixture Problem. I need help! I need to label a table chart and then set up an equation using the expression in the table, solve for the unknown, and answer the question in the problem statement. The question is fresh green beans cost $2.00 per pound. An eight ounce (1/2 pound ) can of Happy Harvest beans is on sale for 60 cents. How many pounds of fresh green beans can you mix with four cans of Happy Harvest beans if you want to keep the cost of the dish to $1.50 per pound??

2m+1.20n=1.5(m+n)
20m+12n=15(m+n)
20m+12n=15m+15n
5m-3n=0
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation 5+x+%2B+-3+y+=+0 describes a sloping line. For any
equation ax+by+c = 0, slope is -a%2Fb+=+-5%2F-3.
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 0/5 = 0.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 0/-3 = 0.
  • Slope is -5/-3 = 1.66666666666667.
  • Equation in slope-intercept form: y=1.66666666666667*x+0.
