I think that you might have only part of the question here.

After getting approval to do additional fundraising Chris and Lacey decided to participate in a walkathon to raise money for the shelter. Chris walked 5 miles less than twice the number of miles that Lacey walked. The students will collect $18 in pledges for every mile that they walked

Let n represent the number of miles Lacey walked

Write and solve an equation to answer the question "How many miles did Lacey walk if Chris collected $450 in pledges?
18(x)=450
x=25

To answer the question of how many miles Lacey walked, you need additional information or context. The equation 18(x) = 450 implies that Lacey collected $450 in pledges. However, without knowing the value of x (the amount that each mile is worth in terms of pledges), it is not possible to determine how many miles Lacey walked solely based on this equation.

Similarly, without any additional information, it is not possible to determine how many miles Chris walked.
