C. 4 weeks

Step-by-step explanation:

Trish and Aria are walking to raise money for the school library. Trish has walked 38 miles and walks 10 miles each week. Aria has walked 30 miles and walks 12 miles each week

After how many weeks will Trish and Aria have walked the same number of miles? A. 2 weeks B. 3 weeks C. 4 weeks D. 5 weeks

Trish = 38 + 10x

Aria = 30 + 12x

Where,

x = number of weeks

After how many weeks will Trish and Aria have walked the same number of miles?

Equate both equations

38 + 10x = 30 + 12x

38 - 30 = 12x - 10x

8 = 2x

x = 8/2

x = 4 weeks

the answer to the expression is 83
