*Make sure to use the SYW section and label/create a table for your calculations*
More Mancini Mart--Many customers went to Mancini Mart and bought different amounts of candy.
CFS:
#1: Accurately identifies the constant of proportionality
#2: Writes an accurate equation using appropriate variables
#3: Uses equation to extend the proportional relationship
Given the ordered pair (2, 5), which of the following are the constant of proportionality?
Nature--Mr. Espinoza went hiking in Berkeley over the weekend.
CFS:
#1: Accurately identifies the constant of proportionality
#2: Writes an accurate equation using appropriate variables
#3: Uses equation to extend the proportional relationship
Identify 1 ordered pair (x,y) of the points on the graph
What is the constant of proportionality for this graph?
Write an equation to represent the proportional relationship with distance in miles, m, and time in hours, h.
How far can Mr. Espinoza hike if he is out for 4 hours in the morning?
"If Mr. Espinoza is hiking for 4 hours..."
Emergency--A hurricane touched down in Florida last week, leading to floods and evacuations. The height of the water increased at a constant rate.
CFS:
#1: Accurately identifies the constant of proportionality
#2: Writes an accurate equation using appropriate variables
#3: Uses equation to extend the proportional relationship
What is the constant of proportionality for this graph?
Write an equation to model the relationship using i for inches of water and d for the number of days.
**You must use Formative's SYW section and make a table to calculate**
Predict the height of the water after 15 days. Use your equation from part a)
**You MUST use formative's SYW section to get credit**
Tables––This table shows a proportional relationship between x and y.
Find the constant of proportionality (k). Using the value for k, write an equation in the form of y = kx.
Avocados—Mr. Espinoza’s teacher friend buys avocados very week. At the grocery store, there is a sign that reads “Avocados-- 1 1/2 pounds ONLY $7”
There are a lot of farms around Gilroy. You can pay $9 3/4 for 3 1/4 pounds of avocados. Would you rather shop at the Gilroy farms or at the grocery store? Explain.
Write an equation to represent the relationship between price and pounds of avocados at Gilroy farms.
How much would 8.5 pounds of avocados cost?
Review
Grocery—At Mancini Mart, 3 1/3 pounds of smelly cheese is $10 1/2. At Ms. P’s Place, 2 1/2 pounds of the same smelly cheese if $6 1/4.
Which store sells smelly cheese at a better value?
Write an equation for the cost of smelly cheese from Ms. P’s Place. How much does 3.5 pounds of cheese cost?
The graph below shows the weight of several objects in both pounds and ounce
Which statement BEST explains whether the graph represents a proportional relationship?
a) Write an equation to represent the proportional relationship with total cost, c, and pounds of candy, p.
**You must use Formative's SYW section and make a table to calculate**
b) Prove that your equation is correct using values from the graph/table.
c) How much would it cost you to get 9 pounds of candy for Halloween?
"9 pounds of candy would cost..."
