Question

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: (2 points) 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

Answer 1

Answer:

A=1000 so now the equation is

700(1000)+1200R=1,000,000

700,000+1200R=1,000,000

subtract 7000,000 to get:1200R=300,000

then divide by 1200 to getR=250
