Writer A vs Writer B: Fractional Page Output Analysis

Question

Writer A writes 35 \frac{3}{5} of the number of pages writer B writes per day. Both of them together write more than 200 pages per day.

What can be said about the number of pages that writer A writes per day?

Step-by-Step Solution

To solve the problem, we need to analyze the inequality involving the pages written by Writers A and B:

First, let xx represent the number of pages Writer B writes per day. Then, the number of pages Writer A writes is given by the expression 35x\frac{3}{5}x.

The problem states that together they write more than 200 pages per day. Therefore, we can set up the inequality:

35x+x>200. \frac{3}{5}x + x > 200.

We need to simplify and solve this inequality:

  • Combine the terms on the left-hand side:
35x+55x=85x. \frac{3}{5}x + \frac{5}{5}x = \frac{8}{5}x.

Substituting this back into the inequality:

85x>200. \frac{8}{5}x > 200.

To solve for xx, multiply both sides of the inequality by 58\frac{5}{8} to isolate xx:

x>200×58. x > \frac{200 \times 5}{8}.

Perform the multiplication:

x>10008=125. x > \frac{1000}{8} = 125.

This implies that the number of pages xx written by Writer B should be greater than 125.

Substitute x>125x > 125 back to find the pages written by Writer A:

Pages by A=35xPages by A>35125=75. \text{Pages by A} = \frac{3}{5}x \quad \Rightarrow \quad \text{Pages by A} > \frac{3}{5} \cdot 125 = 75.

Therefore, Writer A writes more than 75 pages per day.

The correct answer is:

More than -75

Answer

More than 75
