Isiah needs to save an additional [tex]\$50[/tex] for 9 months to save [tex]\$ 1000[/tex]
Let there are two integers [tex]p, q[/tex] and we will write these integers in the format of [tex]\frac{p}{q}[/tex], where [tex]q \neq0[/tex].
Isiah has the amount [tex]\$550[/tex] and he needs to save an additional [tex]\$50[/tex] every month.
His target is to save [tex]\$1000[/tex] for a trip.
Now, he needs to save the amount of [tex]\$1000-\$550[/tex]
[tex]=\$450[/tex]
In a month he will be able to save only [tex]\$50[/tex]
Now, for finding the required result, we need to divide [tex]\$450[/tex] by [tex]\$50[/tex].
The number of the required months will be [tex]\frac{450}{50}[/tex]
[tex]=9[/tex] month.
Therefore, Isiah needs to save an additional [tex]\$50[/tex] for 9 months
