Answer:

Option C is correct.

Step-by-step explanation:

Given is :

The value of Ari's rolls of coins is = $113

The coins are pennies, dimes, nickels and quarters.

Total money is represented by = penny + nickle + dime + quarter  All values in dollars are represented by:

113 = .01* pennies + .05* nickles + 0.1* dimes + 0.25* quarters  

Further calculating we get,

113 = .01* 50*penny rolls + .05 * 40*nickle rolls + .1 * 50*dime rolls + .25 * 40*quarter rolls  

113=.5p+2n+5d+10q

where p is the number of penny rolls, n is the number of nickle rolls, d is the number of dime rolls, and q is the number of quarter rolls  

Now checking all the options by putting values.

A. 113=.5(5)+2(8)+5(4)+10(7)

113\neq 108.5

B. 113=.5(4)+2(8)+5(7)+10(5)

113\neq 103

C. 113=.5(4)+2(8)+5(5)+10(7)

113=113

D. 113=.5(5)+2(8)+5(7)+10(4)

113\neq 93.5

Therefore, option C is the right option.

An odd number of rolls of pennies ($0.50 each) cannot be part of the solution, making answers A and D not worthy of consideration.

The correct choice is C.

Jane and Sammie are making decisions about their bank accounts. Jane wants to deposit
prisoha [69]

Answer:

<u><em>Sammie</em></u>

Step-by-step explanation:

<u><em>Jane</em></u>

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 550.00(1 + 0.05/4)(4)(10)

A = 550.00(1 + 0.0125)(40)

A = $903.99

<u><em>Sammie</em></u>

First, convert R as a percent to r as a decimal

r = R/100

r = 7/100

r = 0.07 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 550.00(1 + 0.07/12)(12)(10)

A = 550.00(1 + 0.005833333)(120)

A = $1,105.31
