Mateo has been studying after school while preparing for a test retake. His work paid off ! His score on the retake was a 94. This was quite a difference from the grade on his first attempt which was a 68. What is the approximate percent of change between the two tests?

28%

Step-by-step explanation:

We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.

First, subtract the two numbers

94 - 68 = 26

Put 26 over 94 to make this 26/94

Divide to get 0.28 (simplified and rounded)

So the increase was 28%

increase of 28?

Step-by-step explanation:

Okay so, I believe it is 28, let me explain. First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100. If the answer is a negative number, this is a percentage increase.

< 6 cm to > 26 cm i believe

step-by-step explanation:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
