Answer:
100
Step-by-step explanation:
take the words 5 more or plus 5+, than twice (2) a number or the amount the old machine can use (x). put it together to get 5+2x now the new one can produce 205 copies total. we use total as equal so, 5+2x=205, subtract 5 on both sides. 2x=200 and divide by 2 to both sides. x=100
To find out how much each book cost first we will subract to find out how many 2 books cost. Then we will divide. last but not least we will check our wok. Lets do it:-
30 - 8.95 = <span>21.05
</span><span>21.05 - 7.25 = 13.80
</span>
CHECK OUR WORK:-
13.80 + 7.25 = 21.05
21.05 + 8.95 = 30
We were RIGHT!!!
Now lets divide:-
13.80 ÷ 2 = 6.90
1 book costs $6.90.
CHECK OUR WORK:-
6.90 × 2 = 13.80
We were RIGHT!!!!
So, 1 book costs $6.90.

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 :)
