Ok so
1/4 of total eaten
3/4 left
3/5 of 3/4 eaten
9/20 left
18=9/20 of whole
multiply both sides by 20
360=9 of whole
divide both sides by 9
40=whole
40 total originlly
Here’s how you can set up the problem:
10 + 25d = 40 + 10d
(d means pages per days)
15d = 30
D = 2
So, the answer would be two days. You can check this by plugging it into the problem:
10 + 25(2) = 40 + 10(2)
10 + 50 = 40 + 20
60 = 60; correct!
Hope this helped! :)
Answer:
The answer to
1. 22/5
2. 3
Step-by-step explanation:
Answer:
4/15 pages per minute
Step-by-step explanation:
10 2/3=32/3
(32/3)/40
(32/3)(1/40)=32/120
simplify
4/15
Answer:
220
Step-by-step explanation:
Let us assume that x number of necklaces are to be fixed to break even i.e. cost price = profit.
Now, cost for x necklaces is 35x + 1650, and selling price is 85x. {As per given condition}
Therefore, profit will be = 85x - (35x +1650) =50x -1650
Hence, to make break even, the condition is
50x - 1650 = 35x + 1650
⇒15 x =3300
⇒ x =220.
Hence, 220 number of necklaces must the jeweler fix to break even. (Answer)
