On friday morning, the tempurature dropped 2 degrees per hour for 4 hours. write and solve and equation to find the total number of degrees d the tempurature dropped on friday morning.

$2100

Step-by-step explanation:

After 500 cards, there is a discount.  

(1100/500 = 2.2) So, $2.20 per card for the first 500 cards.

For every 150 cards after the initial 500, it costs $300, or $2.00 per card.  (300/150 = 2)

If you want 1,000 cards, you are ordering 500 of them at $2.20 per card and the second 500 cards at $2.00 per card.

(500x2.2) + (500x2)= 2100
