To write an inequality, let's use the variables h for the number of hours Ziggy worked and t for the amount earned in tips.
We know that Ziggy earned $7.50 per hour and an additional $100 in tips. So, the amount he earned in total, E, can be expressed as:
E = 7.50h + 100
We are also given that Ziggy earned more than $145 in all. Therefore, we can write the inequality as:
E > 145
Substituting the expression for E in terms of h and t, we have:
7.50h + 100 > 145
Simplifying the inequality, we have:
7.50h > 45
Finally, to solve for 'h', we can divide both sides of the inequality by 7.50:
h > 6
Therefore, the inequality to show the possible amount of hours Ziggy may have worked on Saturday is h > 6.
