Kerrie uses the work shown below to determine 35% of 280.

step 1: 35% = 10% + 25%

step 2: 10% of 280 = 280: 10 = 28

step 3: 25% of 280 = 280 : 4 = 70

step 4: 28 + 70 = 98

she states that 35% of 280 is 98. which is a true statement about kerrie's solution?

kerrie's solution is correct.

kerrie incorrectly determined 10% in step 2.

kerrie incorrectly determined 25% in step 3.

kerrie incorrectly combined the solutions from step 2 and step 3 in step 4.

For this case we must find 35% of 280.

Kerrie gets 10% and then 25%. So:

10% of 280:

280 ------------> 100%

x -----------------> 10%

Where "x" represents the amount given by 10% of 280.

Thus, 10% of 280 is 28.

Now, we find 25% of 280:

280 ------------> 100%

x -----------------> 25%

Where "x" represents the amount given by 25% of 280.

Thus, 25% of 280 is 70.

So we have that 35% of 280 is given by:

So, Kerrie's solution is correct.

Option A

Step-by-step explanation:

Each step of Kerrie's solution is correct, because 10% + 25% is actually 35%. Also, 10% of 280 is 28, because we divide 280 by 10. The third step is also correct because 25% is the same as the fourth part, or divide by four, because 25% is the fourth part of 100%.

At last, the sum 70 + 28 is also correct, because it results in 98.

Basically, Kerrie made a different process, but it gives the same result. Because we only could do it like this:

Then,

As you can see, it results the same number.

0.5 meters per second

step-by-step explanation:

the average speed between 2 seconds and 8 seconds is 0.5 meters per second.
