Amy has $1,000 in a savings account at the beginning of the fall. She wants to have at least $500 in the account by the end of the fall. She withdraws $100 a week for living expenses. Write an inequality for the number of weeks Amy can withdraw money, and solve.

Question

A) 1000 - 100w ≤ 500; w ≥ 6
B) 1000 + 100w ≤ 500; w ≤ 5
C) 1000 + 100w ≥ 500; w ≥ 6
D) 1000 - 100w ≥ 500; w ≤ 5

Answer 1

Did you look at the choices?
The left side of the statements describe the amount she has left.
Since she want to keep a balance of more than 500, choices A and B are obviously eliminated.

So look at C and D
in C she would be adding 100 per week (+), but she withdraws 100 (-)

so .....
