35 ÷ 7 = 5
So the money is going to double 5 times.
300 = 600
600 = 1,200
1,200 = 2,400
2,400 = 4,800
4,800 = 9,600
So she would have $9,600 at the end.
Hope it helps!
Let's present a solution for the generic case.
The equation will be of the form y=ax+b
If (7,3) is on it, then 3=7a+b
If (14,6) is on it, then 6=14a+b
Now we have a system we can solve.
3=7a+b => b = 3-7a
6=14a + 3-7a => 3 = 7a => a=3/7
b = 3-7*3/7 = 0
So y = (3/7)x is the equation.
Answer:
I don't know the answer
Step-by-step explanation:
Divide 2.80 by 2
2/5 because it’s the same as 4/10
1/4 because it’s 5/20 and 1/5 is 4/20
they are both the same because 3/4 is the same as 18/24
hope that helps!
Answer:
Step-by-step explanation:
Cost is 1200 rupees
<u>Desired gain is 1/3, which is:</u>
<u>Selling price is:</u>
<u>Marked price is x, and 1600 is the discounted price by 20%:</u>
- x - 0.2x = 1600
- 0.8x = 1600
- x = 1600/0.8 = 2000 rupees
