Answer 8

A store mixes Kenyan coffee worth $11 per kilogram and venezuelan coffee worth $14 per kilogram. The mixture is to sell for $12 per kilogram. Find how much each should be used to make 276 kilo.

Answer 9

Kenyan Coffee, $11/kilo--> amount needed is "k"
Venezuelan coffee, $14/kilo--> amount needed is "v"
k + v = 276, so v = 276 - k
$11k + $14v= $12(276)
Using these two equations that we got from the information given... We can solve for k
11k + 14(276-k)=12(276)

Answer 10

ok so after i do that then what?

Answer 11

You need to isolate k, meaning get it all by itself. The first step is distributing 14 to 276 and -k.

Answer 12

do you need more specific help?

Answer 13

11k + 14(276-k)=12(276)
11k + 3864 - 14k=3312
11k-14k=3312-3864
-3k=-552
k=-552/-3
k= 184 kilograms of Kenyan coffee needed for the mixture

v=276-184
v=92 kilograms of Venezuelan coffee needed for the mixture
