Afarm grew 19.8 tons of wheat in 2013. the farm’s wheat output increased by 9.8% from 2013 to 2014 and by 5.1% from 2014 to 2015. which expression represents a strategy from estimating the total output of wheat, in tons, in 2015?
a)20+10+5
b)20(10)(5)
c)20+1.1+1.05
d)20(1.1)(1.05)

D

Step-by-step explanation:

For simpler calculation, we can round up the numbers.

Let's take 19.8 as 20, 9.8% as 10%, and 5.1% as 5%.

In 2014, 20 tons increased by 10%, so we would need to multiply 20 by 1.10 (this is 10% increase).

In 2015, we would need to increase the quantity "20(1.10)" by 5%, which means we would multiply that quantity by 1.05.

So, now we have 20(1.10)(1.05). This is equal to option D.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
