We all know numbers under 10 are spelled out and numbers over 10 are not. But what about when I mix the two in one sentence? "My five years of experience counts for more than your 20." Or, "I have four cars with over 100,000 miles, six with 10,000 miles and 11 with only five miles."
My understanding has always been that if any number in the sentence is above 10, then all numbers are expressed as a number.
They read OK to me; however, I would drop the 's' in 'counts'.
