Dollars Earned = y

Dollars Saved = x
Equation : y=4x+100
My problem :
For each increase of $200 in earnings, what is the increase in savings?
PLEASE ANSWER FAST I HAVE 10MINS

To find the increase in savings for each increase of $200 in earnings, we first need to understand the equation y = 4x + 100. This equation represents a linear relation between dollars earned (y) and dollars saved (x), where the earnings are four times the savings plus an additional $100.

To solve the problem, we need to determine the rate of change between earnings and savings. Looking at the equation, we can see that for every dollar increase in savings (x), earnings (y) increase by 4 dollars. This means that the slope of the equation is 4.

In this scenario, if earnings increase by $200, we can calculate the corresponding increase in savings using the slope of the equation.

Step 1: Determine the slope of the equation:
The slope of the equation y = 4x + 100 is 4.

Step 2: Calculate the increase in savings:
Since the slope is 4, we can calculate the increase in savings for each increase of $200 in earnings by dividing $200 by the slope (4):
Increase in Savings = $200 / 4 = $50

Therefore, for each increase of $200 in earnings, the increase in savings is $50.
