Solving inequalities is almost the same as solving equalities for basic cases. Only thing you've to watch out for is signs.
For example, in 2x + 3 > 5,
We may subtract 3 from both sides,
2x > 2
Hence, by dividing both sides by 2, we get x>1.
The inequality sign changes on multiplying with (-)
For example, 2 < 6
But, -2 > -6
And when you interchange a fraction
E.g. 3/4 > 2/3
But, 4/3 < 3/2
You can now solve these of your own

To calculate what is better deal we need to calculate how much 1 pound of dog food costs at both shops.
First shop:
4.99/20 = 0.2495$/pound
Second shop:
12.50/50 = 0.25$/pound
This means that first shop had slightly better deal since at that place pound was a bit less expensive.
1 kilogram = 2.2 pounds.
Multiply the total kilograms by 2.2 to get total pounds.
31.5 kilograms x 2.2 = 69.3 pounds
