Ill give you my points and brainlest first to answer

A). Adam and Bianca is saving the same per day and it is 3$/day

B). On starting of competitions,

     Adam has 3$ and Bianca has 2$

Step-by-step explanation:

Given that saving of Adam is shown in graph and saving of Bianca is shown in the table.

In the case of Adam's saving

Equation of line for saving is given by y=mx+c

y is saving in dollars and x is a number of days.

where m is a slope of line and c is the y-intercept

The slope is given by m=

From a given graph of Adam's saving,

A line passing through, (0,3) and (1,6)

The slope is given line will be  

m1=

m1=

m1=3

and y-intercept of the graph is c=3

Therefore, The equation for Adam's saving is y=3x+3

.

In the case of Bianca's saving

Equation of line for saving is given by (y-Y1)=m(x-X1)

y is saving in dollars and x is a number of days.

where m is the slope of the line

The slope is given by m=

From the given table of Bianca's saving,

A line passing through, (5,17) and (8,26)

The slope is given line will be  

m2=

m2=

m2=3

Therefore, The equation for Bianca's saving is

(y-Y1)=m(x-X1)

(y-17)=3(x-5)

y-17=3x-15

y=3x+2

A). Determine who saves the most per day.

Ans.

On comparing the slope of the equations

m1=m2=3$/day

Thus, Adam and Bianca is saving the same per day

B). How much money both have starting of competitions

Ans.

On comparing the y-intercept os equations

For Adam: Y-intercept is 3$

For Bianca: Y-intercept is 2$

my guess is
