Allie orders candles from an online company that offers flat rate shipping. She placed an order for 4 candles for $35. A few months later, she placed an order for 12 candles
for $95. Write an equation in point-slope form to model the total cost, y, for ordering x
candles. How much is shipping?
y - 95 = 7.5 (x - 12) y + 35 = 7.5 (x + 4): y + 95 = 7.5 (x + 12) Y - 35 = 7.5 (x - 4):
; shipping is $7.50 shipping is $7.50 ; shipping is $5
