Answer:
$3.84 is the amount you save by purchasing the cheaper lightbulbs when buying 24.
Explanation:
Alrighty, so!
With this one, I broke down the price per lightbulb (divided the money by the amount of bulbs in the package).
$4.96/4= $1.24/bulb
$6.48/6= $1.08/bulb
I then multiplied that amount per bulb by 24.....
$1.24 x 24 = $29.76
$1.08 x 24 = $25.92
.... And subtracted the lower number from the higher number to get the answer.
$29.76-$25.92= $3.84
Hope this helps :D
