Answer 1

Answer:

$0.01p + 0.05n = 8.80; n = 2p$

$P = 80$

$N = 160$

Step-by-step explanation:

Hello!

Equation

We know that there are twice as many nickels as pennies, so we can say that n = 2p.

• $n = 2p$

Given the hint:

• Pennies are worth $0.01
• Nickels are worth $0.05

Since "N" and "P" represent the number of pennies, information that we don't know, we can fill in the blank spaces with the value, information that we do know.

• $?p + ?n = 8.80; n = 2p$
• $0.01p + 0.05n = 8.80; n = 2p$

Solution

Solve for P

We can plug in 2p for "N" in the equation to solve for "P".

• $0.01p + 0.05n = 8.80; n = 2p$
• $0.01p + 0.05(2p) = 8.80$
• $0.01p+0.1p = 8.80$
• $0.11p = 8.80$
• $p = 80$

There are 80 pennies.

Solve for N

We can plug in 80 in the second equation (N = 2p) to solve for N.

• $n = 2p$
• $n = 2(80)$
• $n = 160$

There are 160 nickels.

The equation: $0.01p + 0.05n = 8.80; n = 2p$

# of Pennies: $P = 80$

# of Nickels: $N = 160$
