1. These are the first sentences in the short story, "The Gift of the Magi," by O. Henry: "One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies."

Model the scenario with an equation. Let q be the number of quarters, d be the number of dimes, and n be the number of nickels.

A. 25 q + 10 d + 5 n + 60 = 1.87
B. 0.25 q + 0.10 d + 0.5 n + 0.60 = 187
C. q + d + n + 60 = 187
D. 25 q + 10 d + 5 n + 60 = 187

2. These are the first sentences in the short story, "The Gift of the Magi," by O. Henry:

"One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies."

A. Simplify the equation that represents the value of the coins. Make it an equation that expresses the value of quarters, dimes, and nickels. Show your work.

B. Is it possible to have exactly 60 pennies in $1.87? Explain.

I will give brainliest if correct. This question has 3 parts please give me three answers
