Question

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

Step 1: 35 percent = 10 percent + 25 percent
Step 2: 10% of 280 = 280 divided by 10 = 28
Step 3: 25% of 280 = 280 divided by 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.
