ving table indicates the U.S. Postal Rates for large envelopes and packages of different weights: Weight, Not Over (ounces) Cost to Mail a Large Envelope ($) 1 0.88 2 1.08 3 1.28 4 1.48 1.68 1.88 2.08 2.28 5 6 7 8 Cost to Mail a Package ($) 1.71 1.71 1.71 1.88 2.05 2.22 2.39 2.56 d. Create a linear model that could be used to calculate the cost to mail a large envelope, given its weight in ounces. Use L to represent the cost to mail a large envelope and a to represent the envelope weight in ounces. (In reality, weights are rounded up to the nearest whole ounce) L e. Create a linear model that could be used to calculate the cost to mail a package, given its weight in ounces. Use P to represent the cost to mail a package and a to represent the package weight in ounces. (This will require two linear pieces.) If a is a whole number between 1 and 3, then the model is P = AG If x is a whole number over 3 and not over 8, then the model is P = f. Find the weight at which a large envelope and a package will cost the same amount to mail, assuming your linear models still apply to higher weights. Round to the nearest tenth of an ounce (1 decimal place).
