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

given that a mixture contain 1000 pounds of Arabica beans so us this value substitute it inside equation and so in this way try calcule the value of R

Answer 2

do you understand me ? please collaborate

Answer 3

that all the test gave me and i am so lost on how to slove it

Answer 4

do you see above given this equation

700A + 1200R = 1,000,000

and you know that the value of A = 1000

so just substitute this 1000 in place of A inside equation and from this calcule the value of R

Answer 5

what i am still lost

Answer 6

700A + 1200R = 1,000,000

please rewrite this equation so that in place of A write 1000

Answer 7

@jorellcross do you understand me ?

Answer 8

100a+1200r=1000,000

Answer 9

yes this is the equation what you need using but for you can calcule the value of R you need substitute in place of A this given value what is 1000

Answer 10

no sorry you ve wrote wrong this equation

here is correct

700A + 1200R = 1,000,000

Answer 11

what you get than in place of A write 1000 ?

Answer 12

you got me even more lost

Answer 13

@jorellcross ?

Answer 14

700A + 1200R = 1,000,000

so substitute this given value of A in place of A and will get

700*1000 +1200R = 1000000

yes ?

Answer 15

ohhh boy

Answer 16

and now how you get the value of R ?

Answer 17

@Apple0291 700*1000 = ?
