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 ??

Re: Mixture With Prices Question

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?

Re: Mixture With Prices Question

Okay so i did a little thinking and i realize that if I just 1.2+2.1 = 3.3 which is the answer.
