Which is the better buy? Find the unit rate for each meat. Show your work and explain reasoning.
KATRIN_1 [288]

You start by changing the fraction into a decimal.

4.5 lb. of ground beef= 16.11

6.25  lb. of ground turkey= 18.50

Next, you divide the amount they cost by the pounds to get the price per pound.

16.11÷4.5= 3.58

18.50÷6.25= 2.96

So, a pound of beef is $3.58, and a pound of turkey is $2.96.

The turkey is 62 cents less than the beef per pound.

That means the turkey is a better buy! :)


(Have a good day! :))

(-11)-((-7)+5<br> help me solve please !!
nekit [7.7K]

Answer:

1 or -9, depends on the problem, see below.

Step-by-step explanation:

-11--7+5

Two negatives make a positive so our new equation is:

-11+7+5

-11+7 is -4, so:

-4+5

And this leaves us with:

1

But I saw there was a parentheses, was it misplaced or was one not added? If one was not ended to the end, then the answer would be different.

(-11)-((-7)+5)

-7+5 is negative 2, so:

-11-(-2)

Once again, two negatives make a positive, so our new equation would be:

-11+2

Which gets us:

-9
