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

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
