Multiply the amount of the notebooks which is 3, by the cost of the notebook, which is $15.85. that is $47.55.
to find how much it costs with the coupon, do the notebook cost and subtract that by 0.75
$47.55 - 0.75 = $46.8
Markup=10.82(72/100)≈$7.79 (to nearest cent)
retail=10.82(100+72)/100≈$18.61 (to nearest cent)
Temperature will be plotted on the y-axis
