Graph the system of equations on your graph paper to answer the question.

1 answer:

4 0

Y= x-4: gradient is 1 ; y- intercept is -4
g= -3+6
g= 3: y-intercept is 3; gradient is 0
Then you graph it
After graphing it you should find the intersection of this two line which I marked on the graph.
I’m not sure if the question is just asking you to show how these two functions are expressed on a graph or does it actually ask you to find the intersection of the two lines
But yea the coordinates of the intersection is (7,3)

Answer:

a) UNIT PRICE of potatoes is $0.56

b) UNIT PRICE of broccoli is $3.1

c) UNIT PRICE of broccoli is $0.98

Step-by-step explanation:

UNIT PRICE is defined as the price of 1 unit.

$\textrm{Unit Price} = \frac{\textrm{Total cost on n products}}{\textrm{n}}$

Now, here in the given question:

1. Cost of 4.5 pounds of potatoes is $2.52

So, the unit price of potatoes $= \frac{\textrm{2.52}}{\textrm{4.5}} = 0.56$

⇒ 1 pound of potatoes cost $0.56

Hence,UNIT PRICE of potatoes is $0.56

2 Cost of 2.5 pounds of broccoli is $7.75.

So, the cost of 1 pound of broccoli $= \frac{\textrm{7.75}}{\textrm{2.5}} = 3.1$

⇒ 1 pound of broccoli cost $3.1

Hence,UNIT PRICE of broccoli is $3.1

3. Cost of 2.5 pounds of pears is $2.45.

So, the cost of 1 pound of pears $= \frac{\textrm{2.45}}{\textrm{2.5}} = 0.98$

⇒ 1 pound of pears cost $0.98

Hence,UNIT PRICE of broccoli is $0.98

The drama club collected $198.75

The answer is reasonable because 75% of 212 is 159 and each ticket costs $1.25. So 159 tickets for $1.25 each is $198.75
