q=quarters
if she has 12 coins then
12-d=q she has 12-d quarters

A bad contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 14% are pennies are 32% are dimes
Contact [7]

Answer:

$6.22

Step-by-step explanation:

Given;

Total number of coins N = 50

Number of pennies p = 14% of N = 0.14 × 50 = 7

Number of dimes d = 32% of N = 0.32×50 = 16

Number of nickels n = 4 + number of pennies = 4+p

n = 4+7 = 11

Number of quarters q;

N = p+d+n+q

q = N - (p+d+n)

q = 50-(7+16+11)

q = 16

1 Penny = 1 cent = $0.01

1 Nickel = 5 cent = $0.05

1 dime = 10 cents = $0.10

1 quarter = 25 cents = $0.25

Total amount in the bag is;

C = 0.01p + 0.05n + 0.10d +0.25q

Substituting the values;

C = 0.01(7) + 0.05(11) + 0.10(16) + 0.25(16)

C = $6.22

The bag contains $6.22

What is the answer to thiss
lana [24]

Hi Student!

This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression.  So let's plug in the values and solve.

<u>Plug in the values</u>

  • m^2 + 5
  • (9)^2 + 5

<u>Factor out the exponent</u>

  • (9*9) + 5
  • 81 + 5

<u>Combine</u>

  • 86

Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.
