1 meter is the same as 100 centimeters, so since Liz jumped 100 centimeters, and Alana jumped 132, Alana jumped higher.
So let's call x the amount of ounces in Solution A
So then the equation would look something like this.
0.65(x) + 0.9(130-x) = 0.7(130)
To make it easier, multiply both sides by 100:
65(x) + 90(130-x) = 70(130)
multiply.
65x + 11700 - 90x = 9100
Make sure that x is on one side and the numbers are on the other:
-25x = -2600
The negatives cancel out:
25x = 2600
Solve for x:
x = 104.
So then Solution A has 104 ounces, and Solution B has 130 - 104 ounces, which is 26 ounces.
