The cost of a long-distance phone call, in cents, can be modeled by the ceiling function whose graph is shown. how much does it cost to talk for 3.1 minutes? 2 cents 3 cents 4 cents 5 cents

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

m∠a is 90°

m∠b is 40°
