Kerrie uses the work shown below to determine 35% of 280.Step 1: 35% = 10% + 25%Step 2: 10% of 280 = 280:10 = 28Step 3: 25% of 280 = 280 : 4 = 70Step 4: 28 + 70 = 98She 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.[tex]x = \frac {10 * 280} {100}\\x = 28[/tex]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.[tex]x = \frac {25 * 280} {100}\\x = 70[/tex]Thus, 25% of 280 is 70.So we have that 35% of 280 is given by:[tex]28 + 70 = 98[/tex]So, Kerrie's solution is correct.Answer:Option A
