Irene bought six pounds of fish for $12.90. based on that cost, how much would 3.4 pounds of the same fish cost? a) $2.15 b. $6.45 c) $7.31 d. $22.76 .

B. 6.45

Step-by-step explanation:

So we know that you bought six pounds for $12.90, and you need to know how much it would cost for three pounds. You need to find out what one pound would cost, then multiply that by three.

You would do:

12.90 ÷ 6

Which equals : 2.15

Then take that and multiply it by 3:

2.15 × 3

Giving you 6.45.

Thus leading to, this fish would cost $6.45 for three pounds.

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
