Last month Maria hiked a total of 90 miles on two trails: a 5-mile mountain trail and a 10-mile canal trail. Let x represent the number of times Maria hiked the mountain trail, and let y represent the number of times Maria hiked the canal trail.

Which equation can be used to find the number of times Maria hiked each trail?

x + y = 90
5x – 10y = 90
90 – 10y = 5x
90 + 10y = 5x

Each mountain hike adds 5 miles and each canal hike adds 10 miles, so 5x + 10y = 90. Rearranging gives 90 − 10y = 5x, so the correct choice is:

90 − 10y = 5x
