1: Write an equation for the following situation. (2 pts.)
--Be sure to define your variables!
--NOTE: You are ONLY writing the equation for this question!
Polly Gone has $120 saved already. She wants to save for airfare to visit her friend. The airfare will cost $500 and she can save $60 per week. How many weeks will it take
her to save enough money for the airfare?
(500 - 120) / 60 = x?
Let's define the variables first:
P = amount of money Polly Gone has saved
C = cost of airfare
S = amount of money Polly Gone can save per week
W = number of weeks
The equation for this situation is:
P + S * W = C
Now, let's substitute the given values:
P (amount of money Polly Gone has saved) = $120
C (cost of airfare) = $500
S (amount of money Polly Gone can save per week) = $60
W (number of weeks) = ?
Substituting these values into the equation, we have:
120 + 60W = 500
This equation can be used to find the number of weeks it will take for Polly Gone to save enough money for the airfare.
