A 6-pound bag of dog food costs $15. What is the unit price of the dog food? A. $15 per 6 pounds

B. $2.25

C. $2.50

D. $90 per pound

C

Step-by-step explanation:

  6.5 x=6.5

6.5 x 2 =15

0.5 x 6 =3

0.5 x 1=-.5

0.5 x 2=1.0

0.5 x 4=2.0

0.5 x 5=2.5

0.5 x 6=3.0 so 6 x 2= 12 adding 3 so 6.5 x 2=15

Hope it helps have a great afternoon:)

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
