A certain brand of coffee comes in two sizes. A 10.5 ounce bag costs $2.99 per ounce. A 29.3 ounce package costs $7.98 find the unit price for each size.

Step-by-step explanation:

Divide the price by the number of units to find the unit price:

  $2.99/(10.5 oz) = $0.2848/oz . . . . smaller package

  $7.98/(29.3 oz) = $0.2724/oz . . . . larger package

i would say c is the best answer, hope it's right!

good luck! =)

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
