Amy can buy an 5-pound bag of dog food for $7.40 or a 4-pound bag of dog food for $5.48. Which is the
better buy?

4-pound bag

Step-by-step explanation:

7.40/5 = 1.48

5.48/4 = 1.37

$1.37 is cheaper

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
