There are 205 coins in a jar all of which are either nickels or
quarters. The value of the coins in the jar is $31.85.
If both of these statements are true, how many nickels are in
the jar?
Enter the answer

There are 97 nickels in the jar

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of coins = 205

Number of nickels = x

Number of quarters = 205 - x

Value of the 205 coins = $ 31.85

2. If both of these statements are true, how many nickels are in  the jar?

Let's solve for x, this way:

0.05x + 0.25 (205 - x) = 31.85

0.05x + 51.25 - 0.25x = 31.85

-0.2x = 31.85 - 51.25

-0.2x = - 19.4

x = -19.4/-0.2

x = 97 ⇒ 205 - x = 108

There are 97 nickels and 108 quarters in the jar

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
