Answer:
97 trays
Please follow along below for an explanation.
Step-by-step explanation:
If a stack of 50 kitchen trays is 7.25 inches tall, how many would it take to make a stack 14 inches tall?
The first step is to divide the 7.25/50 to determine the height of each plate.
The answer to this is 0.145 inches per tray.
Now you need to find how many are in 14 inches.
Divide 14 inches by 0.145 inches to find out how many plates are needed.
You will get an answer of 96.55
You can't exactly have 96.55 serving trays so you need to round to the nearest whole number. Because the decimal is greater than 0.5, you round up.
This gets you to 97 serving trays.
Answer:
Step-by-step explanation:
Let x be the amount at 5%
Then 2200 - x is the amount at 3%
<u>The total interest is:</u>
- 0.05x + (2200 - x)*0.03 = 78.50
- 5x + (2200 - x)*3 = 7850
- 5x + 6600 - 3x = 7850
- 2x = 7850 - 6600
- 2x = 1250
- x = 625
<u>Find the amount at 3%:</u>
Answer: There are 12 white and blue cars more than silver and red cars
Number of white cars: n1=25
Number of blue cars: n2=17
Number of white and blue cars: n3=n1+n2=25+17→n3=42
Number of silver cars: n4=21
Number of red cars: n5=9
Number of silver and red cars: n6=n4+n5=21+9→n6=30
How many more white and blue cars are there than silver and red cars?
n=?
n=n3-n6=42-30→n=12
Answer: There are 12 white and blue cars more than silver and red cars.
