Answer:
The answer is:
275 = 25X + 100
Step-by-step explanation:
1. The equation for the slope- intercept is:
y = mx + b
2. Recognize and value variables
x = number of months
y = the expected range to arrive
m = is the amount Wade earns per month
b = the amount of money saved.
3. Solve the equation for X which is the unknown.
275 - 100 = 25X
175 / 25 = X
X = 7
4. . Show the result
275 = 25(7) + 100
275 = 275
5. Wade will take 7 months to buy your MP3 if he saves 25 for each month.
