Rosemary buys 5 pounds of ground meat for $16.45. How much would 3 pounds of meat cost at the same rate?

$9.87

Step-by-step explanation:

first, find the cost per pound:

$16.45: 5 pounds

divide both sides of the ratio by 5

$3.29: 1 pound

Then, multiply both sides by 3 to find the cost for 3 pounds

$9.87: 3 pounds

9.87

Step-by-step explanation:

5 pounds-> 16.45

1 pound->3.29

3 pounds->9.87

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6

this doesn't make sense lol
