Starting amount: 982 pounds of grain
Since Mr. Parker fed 240 pounds of grain to his pigs, subtract 240 pounds from 982 pounds of grain.
982 - 240 = 742
After feeding pigs: 742 pounds of grain
Mr. Parker fed another 460 pounds of grain to his cows from his 742 pounds, so subtract 460 pounds from 742 pounds.
742 - 460 = 282
After feeding pigs and cows: 282 pounds of grain
Mr. Parker has 282 pounds of grain left.
Answer:
b·h=105
Step-by-step explanation:
u multiply the base times the height
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.
