Question

Mrs Jackson has 14 black pens. this represents 35% of the total amount of pens that Mrs Jackson has. how many pans is Mrs Jackson have

Answer 1

From the question, we're told that Mrs. Jackson has 14 black pens which is 35% of the total number of pens that she has.

Let x represent the total number of pens, our equation will then become;

`(35)/(100)\ast x=14`

Let's go ahead and isolate x by multiplying both sides of the equation by 100 and dividing by 35 afterwards;

`\begin{gathered} 35x=100\ast14 \\ 35x=1400 \\ x=(1400)/(35) \\ \therefore x=40 \end{gathered}`

Therefore, Mrs. Jackson has 40 pens.
