Objective and Summary:
SWBAT interpret graphs to find unit rates as rational numbers (fractions or decimals) and represent with equations
*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.
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**
Check that you do not have spaces in your equation for auto-grading. (unless you have a mixed number)
CFS:
#2: Writes an accurate equation using appropriate variables
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..."
CFS:
#3: Uses equation to extend the proportional relationship
Nature--Mr. Hwung went hiking in Berkeley over the weekend.
a) Write an equation to represent the proportional relationship with distance in miles, m, and time in hours, h.
**You must use Formative's SYW section and make a table to calculate**
Check that you do not have spaces in your equation for auto-grading. (unless you have a mixed number)
CFS:
#2: Writes an accurate equation using appropriate variables
b) How far can Mr. Hwung hike if he is out for 4 hours in the morning?
"If Mr. Hwung is hiking for 4 hours..."
CFS:
#3: Uses equation to extend the proportional relationship
Emergency--A hurricane touched down in Florida last week, leading to floods and evacuations. The height of the water increased at a constant rate.
a) Write an equation to model the relationship using i for inches of water and d for number of days.
**You must use Formative's SYW section and make a table to calculate**
Check that you do not have spaces in your equation for auto-grading. (unless you have a mixed number)
CFS:
#2: Writes an accurate equation using appropriate variables
b) 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**
CFS:
#3: Uses equation to extend the proportional relationship
