arsen [322]

Answer:

The percentage increase in salary of employee is 7.14 %  

Step-by-step explanation:

Given as :

The initial pay of employee = $35,000 per year

The increase pay of employee = $37,500 per year

Let The percentage increase in salary =  X %

So, X  = \frac{increase salary - initial salary}{initial salary}  × 100

Or, X  = \frac{$37,500 - $35,000}{$35,000}  × 100

Or,  X  = \frac{$2,500}{$35,000}  × 100

∴     X = 0.0714  × 100  = 7.14 %

Hence The percentage increase in salary of employee is 7.14 %   Answer

The slope of the linear equation is 20 and the y-intercept is 150

<h3>What is a Slope?</h3>

Slope measures how steep a straight line is. It is described as rise over run.

The slope of the linear equation can be found as follows;

He opens the account with $150 and he plans to save $20 each week. Therefore,

let

x = number of weeks

Therefore,

  • y = 20x + 150

where

y = amount in his account after x number of weeks.

Using the slope intercept equation,

<h3>Slope intercept equation:</h3>
  • y =mx + c

where

m = slope

c = y-intercept

Therefore, the slope of the linear equation is 20 and the y-intercept is 150
