Let d represent the amount of money indollars Ravi must save to reach his goal.445 + d 2 795; d 2350445 + d = 795; d = 350445 + d > 795; d > 350445 + d 2 795; d > 795

Answer 1

Ravi has $445, this is less than his goal, then he needs to add an unknown amount of dollars, d, to the $445 in order to reach his goal. We can represent this by: 445 + d

At least $795, means 795 dollars or more.

Combining this information, we get the next inequality:

445 + d ≥ 795

Subtracting 445 to each side of the inequality, we get:

445 + d - 445 ≥ 795 - 445

d ≥ 350
