Susan read 17 pages today. That is 8 pages fewer than the 1/3 of the pages she read yesterday. How many pages did she read yesterday?!
Let P be the number of pages Susan read yesterday.
17 + 8 = (1/3) * P
Multiplying each side by 3, we get 51 + 24 = P
P = <<75=75>>75. Answer: \boxed{75}.
Let's solve this step by step:
Let's assume the number of pages Susan read yesterday is y.
According to the given information, Susan read 17 pages today, which is 8 pages fewer than 1/3 of the pages she read yesterday.
So, we can write this equation:
17 = (1/3)y - 8
To simplify the equation, let's multiply both sides by 3:
3 * 17 = 3 * ((1/3)y - 8)
51 = y - 24
Add 24 to both sides of the equation:
51 + 24 = y
75 = y
Therefore, Susan read 75 pages yesterday.
To find out how many pages Susan read yesterday, we need to use the information given.
Let's assume that the number of pages Susan read yesterday is x.
We know that Susan read 17 pages today, which is 8 pages fewer than 1/3 of the pages she read yesterday. Mathematically, we can write this as:
17 = (1/3)x - 8
To solve this equation, we need to isolate x by performing the inverse operations.
First, we can add 8 to both sides of the equation to get rid of the -8 on the right side:
17 + 8 = (1/3)x
Simplifying this, we have:
25 = (1/3)x
Next, we multiply both sides of the equation by 3 to eliminate the fraction:
25 * 3 = x
This gives us:
75 = x
Therefore, Susan read 75 pages yesterday.
