The cost of coffee is determined by the type of coffee beans that are mixed together. The cost of a local mix of Arabica and Robusta beans is modeled by the equation below, where A = the pounds of Arabica and R = pounds of Robusta: 700A + 1200R = 1,000,000 If a mixture contains 1000 pounds of Arabica beans, how many pounds of Robusta beans should be in the mixture? R = ________________ pounds

sorry confusing yes getting it no
anonymous
  • anonymous
well you got an equation with 2 unknowns R and A right?
anonymous
  • anonymous
yes
anonymous
  • anonymous
but in your question A is given
anonymous
  • anonymous
that is 1000
anonymous
  • anonymous
ok but r is the confusing part
anonymous
  • anonymous
R becomes then your only unknown
anonymous
  • anonymous
so you fill in your A 700*1000 +1200R = 1 000 000
anonymous
  • anonymous
700 000+ 1200R = 1 000 000
anonymous
  • anonymous
1200R = 300 000
anonymous
  • anonymous
R= 300 000/1200
