The estimate would be 2+3 5+2 and 6+1
so 577
you can also just round and do 250 +300= 550 +20=570
Answer:
Step-by-step explanation:
1) 30 : 100 = x : 299
x = (30 x 299)/100
x = 89,70 $
2) 299 - 89,70 = 209,30 $
3) 5 : 100 = x : 209,30
x = 10,465 $
209,30 + 10,465 = 219,77 $

Answer:
Number of dimes = 34
Number of nickels = 13
Step-by-step explanation:
Total number of coins = 47
Coins are in the form of nickels and dimes.
Value of a nickel = 5 cents
Value of a dime = 10 cents
Total value of coins = $4.05 or 405 cents
To find:
Number of nickels and dimes?
Solution:
Let number of nickels = 
Money value of nickels = 5
Let number of dimes = 
Money value of dimes = 10
Total value of coins = 
This value is given as equal as 405.
As per question statement, the equations can be written as:

Multiplying equation (2) with 5 and subtracting from equation (1):

Number of dimes = 34
Number of nickels = 47 - 34 = 13
