Final answer:
Sammie will make $8 on the sixth week of summer break.
Step-by-step explanation:
To find out how much money Sammie will make on the sixth week of summer break, we need to determine the pattern of her increasing allowance. We know that her allowance increases by one dollar each week. So, to find out how much money she will make on the sixth week, we can add one dollar for each week.
Starting from her initial amount of three dollars, we can calculate: 3 + 1 + 1 + 1 + 1 + 1 = 8.
Therefore, Sammie will make $8 on the sixth week of summer break.
