Hello! I would love to help!
Okay, we know that Raphel has to pay 3,000 dollars in a certain amount of months. Let's let "m" represent the amount of months it will take him.
Now, if we know that he saves 340 dollars a month, we can multiply the unknown amount of months, "m" by 340 to find how many will get 3000.
Here's our equation:
340m = 3000
Alright let's solve for m.
Divide both sides by 340.
340m/340= m
3000/340=8.824
So know we know m= 8.824, or exactly 8.824 months to save 3000 dollars.
However, it is really hard to count 8.824 parts of a month. Let's round it to the nearest whole, nine.
So, that means your answer is 9 months!
Hope this helped! Comment if you have questions!

Step-by-step explanation:
Step-by-step explanation:
Distance = rate × time
If b is the speed of the boat in still water, and c is the speed of the current, then:
60 = (b + c) × 4
35 = (b − c) × 3.5
Simplifying:
15 = b + c
10 = b − c
Add the equations together:
25 = 2b
b = 12.5
Plug into either equation to find c:
c = 2.5
The speed of the boat is 12.5 km/h, and the speed of the current is 2.5 km/h.
