Math - [Lesson 1.15]

Teacher: Mr. Kovalik (408) 314-1092


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.

1

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

1

b) Prove that your equation is correct using values from the graph/table.

1

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.

1

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

1

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.

2

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

2

b) Predict the height of the water after 15 days. Use your equation from part a)
