This is my son's homework for Multiplication and Division Word Problems. The problem didn't say that each cup costs 4.98. It just said 5 cups for 4.98. We added all the cost but we're not sure if we need to multiple the 5 cups to $4.98. And since this is a topic about Multiplication and Division Word Problems, he was confused as to whether we should go for it or vice versa. I would really appreciate the help.<br /><br />Word Problem<br /><br />Alex bought 5 cups for $4.98. He also bought a large plate for $8.75.

<div> </div>
<div>a salt bridge in a battery</div>
<div> </div>
<div>a. causes positive charges to build up where oxidate takes place</div>
<div>b. causes negative charges to build up where reduction takes place</div>
<div>c. allows positive ions to go where there is a buildup of negative charges and negaive ions to go where there is a buildup of negative charges and negative ions to go where there is a buildup of positive charges</div>
<div>d. none of these</div>
<div> </div>
<div>I know salt bridge will help transfer ions but can they be transferred to build ups. Plus I know salt bridge does not prevent build ups.</div>
