Review: Writing and Solving Equations Module 4 Lesson 2

Example 1 Liz has saved $120 towards a vacation and earns $10 an hour working as a cashier. Mike has $200 saved towards his vacation and earns $8 an hour as a waiter. How many hours will they have to work so they have the same amount of money saved? Define the variable: Equation: Work shown to solve: Answer:

Example 2 For a science fair, you perform an experiment to see how the number of Venus flytrap seeds planted in a cup affects plant growth. In each cup, you plant either 5 seeds or 10 seeds. You want to use an equal amount of cups for each seed amount. You have 75 seeds. How many cups do you need? Define the variable: Equation: Work shown to solve: Answer:

Now work on your worksheet. Be sure to follow the directions on the top of each page! Toward the end of the period, we will see if you have any problems with your problems.
