Answer:
She will run 202 miles in 12 wks.
Step-by-step explanation:
y = 17x + 15
15 represents the # of miles she ran in the first week.
17 represents the amount of miles she will run each week
x represents the # of weeks
y = the total # of miles in 12 weeks.
To solve plug in 11 for x since she ran 15 miles the first week she has 11 more to go.
y = 17(11) + 15
y = 187 + 15
y = 202
Hope this helps!
