> will give brainlst

A is positive anD B is negative

Tip: right your name on the line and it determines if it goes up. Or down. If up it’s positive and if it’s negative it goes down.

Step-by-step explanation:

A=300(1+0.035)^t

A=300(1+0.035)^7 = $381.70

A=300(1+0.035)^21 = $617.83

Step-by-step explanation:

It's pretty simple. Use the formula that I posted in the answer. And 1 will always be 1. The decimal comes from the percent. Remember to bring it two places to the left to make a fraction into decimal form. And the t is years. So you raise it to the power of how many years.

Hope this helps
