We need to isolate z on one side of the equation.

First, add 3/7 to both sides of the equation (this will cancel out the -3/7):

2z < 49 + 3/7

Let's change (49+3/7) into an improper fraction:

2z < 346/7

Divide both sides by 2 to get the answer:

z < 173/7

Answer:

$Total = 1.02n$

Step-by-step explanation:

Given

$Earnings = n$

$Raise = 2\%$ --- <em>not 296</em>

$Total = n + 0.02n$

Required

Simplify the expression for total earning

The total amount is derived from:

$Total = Earnings + Raise * Earnings$

$Total = n + 2\% * n$

Express percentage as decimal

$Total = n + 0.02 * n$

Now, we can solve further:

$Total = n + 0.02n$

$Total = 1.02n$

<em>Hence, the simplified expression is 1.02n</em>
