Answer:

4 - pound bag of pears for $14.08

Step-by-step explanation:

To find out which is the better deal, we have to simplify it.

By dividing $14.08 by 4, this gives us the amount of $ each pound costs, which is $3.52.

Now let's find out the amount of $ each pound costs for the 94- ounce bag of pears for $22.56.

First, we need to convert from ounces (oz) to pounds (lbs).

There are 16 ounces in one pound, and we have 94 ounces. So, 94/16 = 5.875 pounds. So there are 5.875 lbs in the $22.56 bag. Now we need to find the amount of $ each pound costs. So we divide $22.56 by 5.875 and we get $3.84.

$3.52 < $3.84 (this is the amount of money each pound of pears cost for each bag). The first bag is cheaper per pound, so they should buy the first one (which is the 4 pound bag btw).

Find slopes , ill mark brainlist
zepelin [54]

Answer:

\frac{3}{2} or 1\frac{1}{2}

Step-by-step explanation:

We are given a graph and asked to find the slope.

So we can see two coordinate points, one on (0, 3) and (2, 0).

When trying to find slope, we use the method rise over run, which basically means y over x as a fraction, in which you then divide.

So count how many times it'll take for x to get to y, base it off the picture below

Since we see our numbers to be divided are 3 over 2, do the division and you get 1 1/2.

Would this be negative though? No, since the graph is in an increase, not a decrease.
