Answer each of the following questions by constructing a multi-step expression based on the given scenarios. Make sure to show your work and provide explanations where necessary.
Scenario 1: A store sells pencils for $2 each and erasers for $3 each. If you buy 5 pencils and 2 erasers, construct an expression to represent the total cost of your purchase.
Scenario 2: You have 15 marbles, and you decide to give away some to your friend. If you give away 4 marbles and then buy 10 more, write an expression to show how many marbles you have left now.
Scenario 3: A recipe calls for 3 cups of flour, 2 cups of sugar, and 1 cup of butter. If you want to double the recipe and then use 1 cup of flour for a different recipe, create an expression to find out how much flour is left after this adjustment.
Scenario 4: You are saving money for a concert. You initially saved $50 and plan to save an additional $20 each week. If you want to save for 8 weeks, write an expression to represent the total amount of money you will have saved at the end of the 8 weeks.
Scenario 5: Your class is collecting cans for a food drive. Each student is asked to bring 6 cans. If there are 10 students and 3 of them decide to bring 2 cans less than requested, express the total number of cans collected.
Remember to clearly show your calculations for each scenario to demonstrate your understanding of multi-step expressions.
