Suppose that you want to mix two coffees in order to obtain 100 pounds of a blend. If x represents the number of pounds of coffee A, write an algebraic expression that represents the number of pounds of coffee B.

Algebraic expression representing number of coffee B = 100-x

Step-by-step explanation:

An algebraic expression is an expression that contains unknowns denoted with alphabets or symbols and natural numbers.

Coffee blend is 100 pounds and x represent number of pounds of coffee A

Hence coffee B = 100-x

Algebraic expression representing number of coffee B = 100-x
