Alma wants to mail a package that requires $1.53 in postage. alma only has 5-cent stamps and 8-cent stamps. what is the smallest number of stamps that she could use to total exactly $1.53?

21 stamps because 8 cents time 16 equals 1.28 and 5 cents times 5 cents equals 0.25 so 1.28+0.25= $1.53

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.
