All this is asking you is to find how much you need to save per month (limit of 5) in order to make your goal of $1200.
To solve this, simply divide 1200 by 5, which is the months, and you get $240, which is how much you have to save per month in 5 moths to reach your exact goal of $1200. If anything is confusing please ask :)
Answer:
the pair solution is : (10;5)
Step-by-step explanation
d + e = 15
....(1)
–d + e = –5
....(2)
add (1) and (2) : 2e =10
e = 5
put the value of : e in (1) or (2) : d + 5 = 15
d = 10
8+5+2+5=20
5 boots = 5/20 or 1/4
1÷4= 0.25
0.25 × 100 = 25%
