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.
To model the scenario, the following will be the numerical coefficients for the variables: 0.05 for nickels (5 cents), 0.10 for dime (10 cents) and 0.25 for quaters (25 cents). Thus the model/equation is, $1.87 = 0.25q + 0.10d + 0.05n + 60.
