Answer:
Gordon recently started jogging. Last week he jogged for 18 minutes. Starting this week, he decided to add 2 minutes to his jog each week. Which of the following equations represents how long his jog will be after x additional weeks?
A.
y = 2x + 18
B.
y = 2x + 20
C.
y = 18x + 20
D.
y = 18x + 2
Step-by-step explanation:
The number of minutes by which he increases his jog, 2, indicates the rate of change.
Since his jog time increases by that amount every week, and x represents the number of weeks, 2 is the value to be attached to the variable x.
Further, the additional minutes added to Gordon's jog have to be added to the original length of his jog in order to determine his total jog time.
Therefore, the equation which represents how long his jog will be after x weeks is y = 2x + 18.
