Simita has 25 coins, consisting of 10c and 5c, which total $2.25. how many of each does she have?​
Ilya [14]

Answer:

10c = 20

5c = 5

Step-by-step explanation:

Let x be the number of 10c coins; let y be the number of 5c coins. The total is $2.25, so the amount of 10c and 5c coins will add to that. Simita has 25 coins, so x and y, the number of coins, will have to add to 25. Hence, solve the simultaneous equation.

10x + 5y = 225 (1) - times by 0

x + y = 25 (2) - times by 5

10x + 5y = 225 (1)

5x + 5y = 125 (2)

Then, take equation 2 away from equation 1.

5x = 100

x = 20

Substitute x back into the original equation.

x + y = 25

20 + y = 25

y = 5

Clarice Sloan is a shift supervisor for Ace

The net pay is the amount left after taxes and deductions have been removed from the gross pay.

Her monthly gross pay is: $4111.93

The deductions are:

\mathbf{FIT = \$102}

\mathbf{SIT = 3.2\%}

\mathbf{CIT = 1.8\%}

Let her gross pay be x.

So, we have:

\mathbf{Net = x - FIT - x \times SIT - x \times CIT}

So, we have:

\mathbf{3804.33 = x - 102 - x \times 3.2\%- x \times 1.8\%}

Express percentage as decimals

\mathbf{3804.33 = x - 102 - x \times 0.032- x \times 0.018}

\mathbf{3804.33 = x - 102 - 0.032x -  0.018x}

Add 102 to both sides

\mathbf{3906.33 = x - 0.032x -  0.018x}

\mathbf{3906.33 = 0.95x}

Divide both sides by 0.95

\mathbf{4111.93 = x}

Rewrite as:

\mathbf{x = 4111.93 }

Hence, her monthly gross pay is: $4111.93
