Answer:
100x=256.25
Step-by-step explanation:
x/1025=25/100
What is 25% of 1025
that would be 1025×25
450 per month
5000-1400=3600
3600/8=450
Since Peter already has 1400 dollars saved you can subtract that form the total amount and since he is trying to get the rest in eight months you just divide the difference by eight.
