Answer:

3.

A. Y = 2x + 30 (red line)

B. Y=5x (blue line)

C. Y=70 (green line)

From 0 to 10 days, choose option B (shown on graph)

From 10 to 20 days, choose option A (first option)

From 20 days and more, choose option C.

4.

surface area of label = 471.2 cm^2

Option A: they pay an initial fee of $30 and lunches cost $2 each

Option B: shown on the graph

Option C: they pay a flat fee of $70 which includes all lunches

A. Y = 2x + 30 (red line)

B. Y=5x (blue line)

C. Y=70 (green line)

b) Describe under what conditions, a student should choose each option. (Hint: you may want to graph all 3 lines on the same axes) (4 marks)

Choose Option A if: Choose Option B if: Choose Option C if:

Least cost is what is below the lowest possible line for the number of days stayed.

From 0 to 10 days, choose option B (shown on graph)

From 10 to 20 days, choose option A (first option)

From 20 days and more, choose option C.

Note that for days 10 and 20, there are two choices each.

The label only covers the curved surface.

Curved surface area

= 2 pi * r * h

= 2 pi (5) * 15

= 150 pi

= 471.2 cm^2
