Answer:
10x + 6 < 125
Explanation:
Hi,
10x is the cost per hat. 6 is the charging fee. 125 is the total cost of the order. We put x because we don't know how many hats they're going to buy. 6 is the amount they pay no matter what. And < is used because the total cost has to be less than 125, not less than or equal to, but LESS than.
Hope this helps
