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.
