Foundations of Mathematical Reasoning, In-Class Activities, Lesson 12.B 86 Theme: Personal Finance Lesson 12, Part B, The cost of driving Jenna's job requires her to travel. She can drive her own 2009 Toyota 4Runner, or she can rent a car. Either way, her employer will reimburse her for mileage. Should Jenna drive her own car or rent one? Part A: What do you need to know to calculate the cost of 1) Jenna's driving her own car? Credit: ellisia/Fotolia Part B: What do you need to know to calculate the cost of Jenna's renting a car? Objectives for the lesson You will understand that: H Units provide meaning to the numbers you get from calculations. O The units found in a solution may be used as a guide to the operations required. You will be able to: O Write a rate as a fraction. OUse a unit factor to convert a rate. O Use dimensional analysis to help determine the factors in a series of operations to obtain an equivalent measure. ent yino qu Jenna's 4Runner is expected to get 22 miles/gallon on the highway, or she can rent a Hyundai Elantra, which gets 40 miles/gallon.27 On her next trip, she will drive 150 miles, and gas is expected to cost $3.59/gallon. 2) Part A: Use your estimation skills to estimate which vehicle would cost more in gas. About how much more? Explain your strategy. Part B: What is the actual cost of the gas for each vehicle? Explain your strategy. 3) What is the total cost of the Elantra if rental is $98.98 plus 15.3% tax? (Gas is not included in this price, and the car must be returned to the agency with a full tank.)

Theme: Risk Assessment 100 Foundations of Mathematical Reasoning, In-Class Activities, Lesson 14.C Lesson 14 Part C, Blood alcohol content Blood alcohol content (BAC) is a measurement of how much alcohol is in someone's blood. It is usually measured as a percentage, so a BAC of 0.3% is three-tenths of 1%. That is, there are 3 grams of alcohol for every 1,000 grams of blood. A BAC of 0.05% impairs reasoning and the ability to concentrate. A BAC of 0.30% can lead to a blackout, shortness of breath, and loss of 1) BAC is usually determined by a breathalyzer, urinalysis, or blood test. However, Swedish physician E.M.P. Widmark developed the following equation for estimating an individual's BÁC. This formula is widely used by forensic 2) biadder control. In most states. the legal limit for driving is a BAC of 0.08%.31 3 scientists:32 2.84.N B =-0.015-t + Credit: zstock/Fotolia W•g Objectives for the lesson You will understand that: O The location of a variable is important to its effect on…

Are the calculations by the student below correct?  IF not, what went wrong?  Explain using mathematical terms/words and correct the error if necessary. Sales A concert promoter wants to book a rock group for a stadium concert. A ticket for admission to the stadium playing field will cost $125, and a ticket for a seat in the stands will cost $175. The group wants to be guaranteed total ticket sales of at least $700,000. How many tickets of each type must be sold to satisfy the group's guarantee? Define variables, set up a mathematical model as a system of linear inequalities, and draw its graph.  Answer: Define Variables:  x = seat in stands and y = seat in playing field; the inequality 125x + 175y ≥ 700,000 models this question and the graph of the solution is below.
