Answer 1

Given

Ravi has $445 in his savings account.

He wants to save at least $795.

Write and solve an inequality to determine how much more money Ravi must save to reach his goal.

To proof

As given

amount of money in dollars Ravi must save to reach his goal be = d

Ravi has in his savings account = $445

He wants to save at least $795

than the inequality become in the form

$445 + d \leq 795\\ 795 - 445 \leq d\\ 350\leq d$

thus $350 Ravi must save to reach his goal.

Hence proved
