Question

Joshua sells a pack of pens for $3.15, which is 5 percent more than he pays for them. Which equation will help find x, the amount he pays for a pack of pens? How many solutions will this equation have?

Answer 1

Explanation:

ONE solution

x = price he pays

1.05x = price at which he sells

1.05x = $ 3.15

x = $ 3.15/1.05

Answer 2

If Joshua sells a pack of pens for $3.15, which is 5 percent more than he pays for them, we can set up the following equation:

1.05x = 3.15

Here, x represents the amount Joshua pays for a pack of pens.

To solve for x, we can divide both sides of the equation by 1.05:

x = 3.15 / 1.05

Simplifying, we get:

x = 3

Therefore, Joshua pays $3 for a pack of pens.

This equation will have only one solution, which is x = 3.
