Step-by-step explanation:

On Monday maggie ran n miles.

On Tuesday, she she ran 90% of the number of miles that she ran on Monday i.e $\dfrac{90}{100}\times n=0.9n$ .

On Wednesday, she ran 50% of the number of miles that she ran on Tuesday i.e. $\dfrac{50}{100}\times 0.9n=0.45n$

First expression : n+0.9n = 1.9 n

Second expression : n + 0.9 n + 0.45 n = 2.35 n

Hence, this is the required solution.
