Whether formally using algebra or informally using logical reasoning, I would reduce the amount of effort required to solve the problem by adding a penny to the cost of each pair of sneakers, making 60 $99 high-tops and $130 low-tops for a total of $6,405.

(1) Formal algebra....

x = # of high-tops
60-x=# of low-tops

The total cost was $6405:

ANSWER: 45 high-top and 15 low-top pairs were sold

(2) Informally....

If all 60 pairs had been high-tops, the total sales would have been 60($99)=$5940.
The actual sales total was $6405-$5940=$465 more.
The difference in price between the high-top and low-top is $31; so the number of low-top pairs sold was $465/$31 = 15.

ANSWER: 15 low-top pairs and 45 high-top pairs were sold.
