Answer:

500

Step-by-step explanation:

First of, multiply all of the number by 10 to remove the decimal place ( this will make it less confusing)

So 102.3 x 10= 1023

4.7 x 10 = 47

You will have to round each of the numbers to 1 significant figure (sf) :

1023 round to 1 sf will be 1000

47 rounded to 1 sf will be 50

Then multiply these numbers:

1000 x 50 = 50000

Finally divide by 100 to get back the decimal places

(You divide by 100 because you multiplied by 10 twice, 10 x 10= 100)

You get 500

Bethany has 3.10$ in nickels and dimes. She has a total of 44 coins . What is the value of the nickels Bethany has
vlada-n [284]
Represent the unknows with n and d.

Then n+d = 44 (# of coins)

and 

$0.05n + $0.10d = $3.10   (value of coins)

Solving the first equation for n, we get n = 44-d.  Subst.  44-d for n in the 2nd equation:

0.05(44-d) + 0.10d = 3.10
Then 2.20 - 0.05d + 0.10d = 3.10, or
          2.20 + 0.05d             = 3.10, or    0.05d = 0.90.  Solving for d, 
       0.90
d = -------- = 18
        0.05

There are 18 dimes and 44-18 nickels.  How many nickels is that?  ;)
