A) 0.01p + 0.05(0.54 – p) = 22
B) 0.01p + 0.05(22 – p) = 0.54
C) 0.01p + 1.1 = 0.54
D) p + 5(22 – p) = 0.54

Answer 1

.01p + .05(22-p) = .54. answer B

Answer 2

Answer with Step-by-step explanation:

Let Ari has p pennies

Ari has a total of 22 coins consisting of pennies and nickels.

Number of pennies+Number of nickles=22

p+Number of nickles=22

So, number of nickles=22-p

1 nickle=$0.05

So, value of 22-p nickles=$0.05(22-p)

and 1 pennies =$0.01

So, value of p pennies=$ 0.01p

The total value of the coins is $0.54.

this means that

0.01p + 0.05(22-p)=0.54

Hence, the equation which can be used to find the number of pennies Ari has is:

B) 0.01p + 0.05(22 – p) = 0.54
