Person A buys 10 granola bars and 6 cups of yogurt for <em>$18</em>
Person B buys 5 granola bars and 4 cups of yogurt for <em>$9.50</em>
Let <u>x</u> represent the granola bars
Let <u>y</u> represent the yogurt
10x + 6y = 18 << ( Divide both sides by 2 )
The second equation is 5x + 4y = 9.50. Now subtract the two equations.
5x + 4y = 9.50
-5x - 3y = -9
y = $.50
5x + 3(.50) = 9
5x + 1.50 = 9
5x = 7.5
x = $1.50

x ----> the number of lions
y ----> the number f tigers
z ----> the number of zebras
we know that
----> equation A
Remember that
To find out the number of lions, multiply the total animals by the percentage of lions
To find out the number of zebras, multiply the total animals by the percentage of zebras
Substitute the value of x and the value of z in equation A and solve for y
