The total number of gifts = x+y.
The inequality is:
Key chains cost $1, Magnets $0.50
Total Cost = x + 0.5y
Inequality is:
Without graphing you can solve system by using substitution:
This is one solution where the maximum x value is given.
So the most keychains that can be purchased is 16. However, because magnets are cheaper, more can be purchased as long as cost remains under 20.
If you solve both inequalities for "y", you get the upper and lower bounds for how many magnets can be purchased given a quantity of keychains.
This is complete solution which gives all possible combinations.

The correct statement about the earthquake in the state is option c. State A had approximately 3,362 more earthquakes than State B.
<h3>How to solve for the earthquake in the state A</h3>we have x/y = 0.00299
y = 163696
To solve for x we have
163696 * 0.00299
= 4895 earthquakes
<h3>Next we have to solve for earth quakes in state B</h3>x = 0.1402 x 10931
= 1533
Next we have to find the difference
4895 - 1533 = 3362 earthquakes.
We have to conclude that state A has 3362 earthquakes more than B. Hence the answer is c.
