Acoffee shop purchased 60 pounds of guatemalan coffee beans and 90 pounds of nicaraguan coffee beans. the total purchase was $180. the next week it purchased 80 pounds of guatemalan coffee and 20 pounds of nicaraguan coffee, and the cost was $100. write and solve a system of equations to find cost per pound of both the guatemalan and nicaraguan coffee beans.

60lbs +90lbs = 150 lbs in total.

$180÷ 150lbs = $1.20 per pound

80lbs+ 20lbs= 100lbs in total

$100 ÷ 100lbs= $1 per pound

So the average cost per pound of the coffee beans is about $1 each
