Can someone help me with this?

Erin bought christmas cards for $2 each to send to her family and friends. which variable is the dependent variable?

Scott’s bank account showed a balance of $750 on sunday. during the next five days, he made one deposit of $140 and numerous withdrawals of $180 each. let x represent the number of withdrawals that scott made. write an inequality that can be used to find the maximum number of withdrawals that scott could have made and maintain a balance of at least $100. do not use a dollar sign ($) in your response.

Solve the inequaliy: (x^2+2)(x−2)^2(6−2x)> 0
