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

1

SPICY--Only try if you have time

Leak--There is a broken pipe in Mr. Hwung's apartment. He measures how much water is leaking over time.

Write an equation to represent the relationship between the time in minutes (m) and the amount of water leaked in gallons (g)

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)
