Notes Over 3.5Modeling a Real-Life SituationModeling a Real-Life Situation8. You are planting an apple orchard and decide to plant two types of trees: McIntosh and Red Delicious. The McIntosh trees cost $20.85 each and the Red Delicious cost $21.25 each. To plant the trees you need to buy a shovel which costs $30 and peat moss which costs $50. Write a model for the total amount you will spend as a function of the number of each type of tree. Evaluate the model for 25 McIntosh trees and 18 Red Delicious trees.T r2521.m8520. 80 25 18
