Answer:
, graph is there for reference.
Step-by-step explanation:
Given,
is the number of math problem Lucy solved.
is the number of pages she read.
She can do each math problem in minutes, therefore she can solve
number of questions into
minutes.
She can read each page in minutes, therefore she can read
pages in 2.5y minutes.
As per given detail,
equation 1.
And,
It is given that number of math problems Lucy solved is 3 times the number of pages she read.
equation 2.
We need to find and
intercept of each of the equation to graph them.
For put y=0
We will get
Thus the point is
Let us find by assuming
we get
Thus the point is
Join these two points.
Similarly considering the other equation
Here x-intercept would be at
We will get
Thus the point is
Let us assume on more point, say , we get
Thus the point is
Join these two points.
We will get a point of intersection at
Thus and
To answer this question you need to first set up the small, medium, large number of cakes as a ratio with a total. From here you will create a new ratio of the correct number of small medium and large Cakes sold using the total 216. The factor would be to multiply by nine. -Step 1 in picture. After this you would read what the relationship is between a medium and a small and the large and the small profits are - Step 2 in picture. After this you would represents the total profit based on the number of small medium and large cakes that were sold. Making this equal to L648.45. To find the profit for one small, you would then divide 648.45 by the 495 you got when you simplify the expression. The answer is L1.31.
