Mr.Brown deposited $2500 to his new savings account. Each month, he deposits $300 to his account. Which inequality can be used to find d, the number of months after opening his account when Mr. Brown will have more than $4000 in his savings account?

X>5

Step-by-step explanation:

Since the initial deposit is given as $2500 then to get more than $4000, Mr. Brown needs additional 4000-2500=$1500

Since each month he deposits $300 then after x months he will have more than $1500 additional.

4000<300x+2500

Collecting like terms

4000-2500<300x

1500<300x

Simplifying

5<x

Or

x>5
