Let small candies

Extra large candies

the number of candies is at least .

Cost of small candy

Cost of extra large candy

but she has only to spend

Solve for

Since number of candies should be integer.

let

total spend which is more than , so this combination is not possible.

She has more so she can buy more small candy.

Hence  small candy

extra large candy

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
