A school store sells pencils for $0.50 each and pens for $1.20 each. On a particular day, the store sold a total of 180 pencils and pens, earning a total of $165.00. Which of the following systems of equations could be used to determine the number of pencils, $p$ , and the number of pens, $n$ , sold?

A.

p + n = 165

0.50 p + 1.20 n = 180

B.

p + n = 180

0.50 p + 1.20 n = 165

C.

p + n = 180

1.20 p + 0.50 n = 165

D.

p + n = 165

1.20 p + 0.50 n = 180
