A Gardner adds 3.5 oz of plant food to 2 gallons of water. The amount he was supposed to add is 4 oz. what is the percent error in mixing the plant food

Thanks. It was 12.5

87.5% or 12.5% not sure sorry

I believe the answer is...He put in 87.5% of what was meant. His error is 12.5%. That is what he is lacking.

no problem

To calculate the percent error in mixing the plant food, we need to compare the amount added to the amount that was supposed to be added.

The formula to calculate percent error is:
Percent Error = (|Observed Value - Expected Value| / Expected Value) * 100

In this case, the observed value is 3.5 oz (amount added), and the expected value is 4 oz (amount supposed to be added).

Using the formula, we can calculate the percent error as follows:

Percent Error = (|3.5 - 4| / 4) * 100
= (|-0.5| / 4) * 100
= (0.5 / 4) * 100
= 0.125 * 100
= 12.5%

Therefore, the percent error in mixing the plant food is 12.5%.
