A example can be Keith has $500 in a savings account at the beginning of the summer. He wants to have at least $200 in the account by the end of the summer. He withdraws $25 each week for food, clothes, and movie tickets. The answer would be Any more than 12 weeks and his account balance would be less than $200. Any number of weeks less than 12 and his account would stay above $200.
X equals 62 because you take 147 and subtract it from 180 and that gives you 33. then you add 33 and 85 together to give you 118. Then you subtract 118 from 180 and that gives you 62. x=62
