The profit on the sale of a bicycle at a bike shop is $30, while the profit on the sale of a tricycle is $20. the owner is interested in making more than $200 in profit per day, and expects to sell at most 9 items per day. the system that represents this situation is b+4≤9 b+4≤9 and 30b+20t> 200 30b+20t> 200 . the graph of the boundary lines is shown below. which region should be shaded (to form the solution)?

Two equations are given

b+t <=9

30b + 20t > 200

WE graph each inequality

b + t <= 9

Make a table for b + t < = 9

b --- > t

0 --> 9

2 --> 7

Plot the point and make a graph. WE shade the bottom region because we have <= symbol

The graph is attached below.

WE graph the inequality

30b + 20t > 200

Make a table for 30b + 20t > 200

b --- > t

0 --> 10

6 --> 1

Plot the point and make a graph. WE shade the upper region because we have > symbol

The intersection of shaded region is our solution.

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
