Answer: B. the variable y represents the pounds of roasted coffee in the 46$ purchase.


Step-by-step explanation:

Given: The rate of espresso = $8.50 per pound

The rate of coffee = $10.25 per pound

The equation represents a online purchase.

@@MATH_TOKEN_0@@ ............(1)

and @@MATH_TOKEN_1@@.................(2)

from equation (2), 8.5 is the coefficient of x, thus variable x represents the pounds of espresso and 10.25 is the coefficient of y, thus variable y represents the pounds of roasted coffee in the total purchase of $46.

And equation (1) represents the total pounds of espresso and roasted coffee.

Hence only option B is correct.
