Mixture With Prices Question
The question is:
Quote:

Growell sells GradeA grass seed at 12cents per ounce and GradeA PLUS for 35cents per ounce.What is the cost of a 1 pound mixture containing 10 ounces of GRadeA with the rest GradeA plus ?
According to the book the answer is 3.30 dollars. But i am getting 0.20 cld anyone tell me what i ma doing wrong. Here is my work

 GradeA seed 10 ounce 10x12 = 120cents or \$1.2 GradeA PLUS seed 6 ounce 6x35=210cents or \$2.1 Mixture 16 ounce Equation
Equation: 16x = 1.2+2.1
16x =3.3
x = \$0.20 Ans
Is this correct ??

As you found out, the grade A part of the pound costs \$1.2 and the grade A PLUS part of the pound costs \$2.1. How much does the whole pound costs?
