Answer 2

The expression that represents the value in dollars of a certain number of pennies, p, and nickels, n is:

Option: a

a. 0.01p + 0.05n

Explanation:

We know that:

100 pennies=1 dollar

i.e.

1 penny=1/100 dollar

i.e.

1 penny=0.01 dollar.

So, if the are p pennies then the price in dollars will be: 0.01p

Also,

20 nickel=1 dollar

i.e.

1 nickel= 1/20 dollar

i.e. 1 nickel=0.05 dollar

so, if there are n nickel then the price in dollars will be: 0.05n

Hence, the total value in dollars is:

0.01p+0.05n
