Answer:
345
Step-by-step explanation:
We can solve this problem by two equations. Our variables will be the following:
is the amount to be multiplied
and
is the amount that should be obtained by multiplying by 43
Thus our <u>first equation</u> is:

But the problem tells us that there was an error and the number
was multiplied by 34, so the result failed by 3105, thus the <u>second equation</u> is as follows:

By multiplying the quantity by 34, an amount is obtained that differs from 3105 from what it would have been obtained if multiplied by 43.
Now we are going to <u>replace the first equation in the second one </u>(
):

And clear to find x:

The number that jimmy was supposed to multiply by 43 is 345.
