Question

Isaac sold 58 of his baseball cards at a collectors show. If this represented 14.5% of his total collection, how many baseball cards did Isaac have before he sold his cards?

Answer 1

`400\ cards`

Explanation:

Let

x------> amount of baseball cards Isaac had before he sold

we know that

`14.5\%=14.5/100=0.145`

so

`0.145x=58`

Solve for x

`x=58/0.145`

`x=400\ cards`
