At a home improvement store, you
decide to purchase a hammer and
a pack of nails. the hammer costs
$8.53. the pack of nails costs $0.87.
what is the total cost? how much
change will you receive if you pay
with a $10 bill? a $20 bill?

$9.40, $0.60, $10.60

Step-by-step explanation:

$8.53 + $0.87 = $9.40

$10 - $9.40 = $0.60

$20 - $9.40 = $10.60

what graph

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
