Question

Elise has budgeted $800 in her checking account to spend during the summer for entertainment. She would like to have at least $200 available at the end of summer. If Elise withdraws $50 per week, which inequality could she use to determine the greatest number of weekly withdrawals (w) she can make without exceeding her budget?

A) 200 + 50w > 800
B) 800 − 50w ≥ 200
C) 800 + 50w ≥ 200
D) 800 − 50w > 200

Answer 1

The answer is B because you are takin away $50 a week. $200 is what she wants to have at the end off the summer. So that automaticly means it is ≥ 200. She is TAKING AWAY $50 a week. Meaning - 50w ≥ 200. Finally she has $800 to begin with. So, 800 - 50w ≥ 200.

Sorry if l am not very well at explaining this kind of stuff. Let me know if you need anymore help!!

Answer 2

The answer is B. Start with the amount she can not go below. 200. That means the the amount can be greater than or equal to $200. Than you have the starting amount(800). Every week you withdrawal(take away) 50. So it would be subtraction. Your inequality would look like B. That is why the answer is B.
