Answer:
Antonio paid $220 for skis he sold for $165, so his profit was $55.
Markup is a percentage increase from the wholesale price,
so let's find the percentage of $55 to $165:
$55/$165 = 33%
.
The temperature starts at 85 degrees.
t = 85
After 1 minute, it loses 3.5 degrees.
t = 85 - 3.5
After 2 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 2
After 3 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 3
etc.
After 12 minutes, it loses another 3.5 times 12 degrees.
t = 85 - 3.5 * 12
