Step-by-step explanation:
Given : $1,500 invested for 20 days at 6.75%, compounded daily.
To find : The amount of interest ?
Solution :
Applying compound interest formula,
Where, A is the amount
P is the principal P=$1500
r is the interest rate r=6.75%=0.0675 compounded daily
t is the time t=20 days

Answer:
The two numbers are 31 and 19
Step-by-step explanation:
Let x and y be the numbers
x+y = 50
x-y = 12
Add the two equations together
x+y = 50
x-y = 12
-----------------
2x +0y = 62
Divide by 2
2x/2 = 62/2
x = 31
Now find y
31+y = 50
Subtract 31
y = 50-31
y = 19
The answer is going to be 68/9 and the fraction is negative.
hope this help!
Rate at which each pumpkin is sold = $5
Rate at which each squash is sold = $3
Let us assume the number of pumpkins sold in a day = x
Then
The number of squash sold on that day = x + 6
Total amount of sales on that day = $98
Then
5x + 3( x + 6) = 98
5x + 3x + 18 = 98
8x = 98 - 18
8x = 80
x = 80/8
= 10
So
The number of pumpkins sold = 10
The number of squash sold = x + 6
= 10 + 6
= 16
You simply need to find the price of one orange at each store, and multiply that by 30.
Store A: 5/3= around $1.67= 1.67*30= $50.10
Store B: 3/2= $1.50= 1.5*30= $45.00
Store C: 9/5= $1.80= 1.8*30= $54.00
Store D: $1.25= 1.25*30= $37.50
As you can see above, at Store D, 30 oranges would only cost $37.50, making it the cheapest store to buy oranges.
I hope this helps :)
