Question

Emma had to finish her 249-page novel by Friday. She had already read 166 pages. Write and solve an equation to show how many pages Emma had left to read by Friday.

p + 166 = 249; p = 83 pages
p − 166 = 249; p = 415 pages
p over 166 equals 2; p = 332 pages
83p = 166; p = 2 pages

Answer 1

p + 166 = 249

p = 83 pages

Explanation:

We know that she has to finish 249 pages novel and read 166.

So, let p represent the number of pages left to read; we have the equation

p + 166 = 249

Now let's solve by subtracting 166 from both sides

p = 83 pages

So, Emma had 83 pages left to read by friday
