Question

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.

Answer 1

$1.87

60 cents in pennies = $.60

Each quarter is $.25, each dime is $.10, and each nickel is $.05.

1.87=q*.25+d*.10+n*.05+.60
