Ken has $950 in a savings account at the beginning of the summer. He wants to have at least $600 in the account by the end of the summer. He withdraws $35 a week for food, clothes and movie tickets. Write an inequality for the number of weeks Ken can withdraw money, and describe the solution.
a. 950 - 35w ≥ 600; w ≤ 10 Eliminate
b. 950 - 35w ≥ 600; w ≤ 11
c. 950 + 35w ≥ 600; w ≥ 10
d. 950 + 35w ≥ 600; w ≥ 11
