27 dollars minus 6 for the ice leaves 21 for hot dogs.. hot dogs are 3 each and 21 dollars left it would be 21 divided by 3 which equals 7
You could solve this mathematically but i mean you could use your eyes.... Its most likely C
;)
Finding the discriminate of a quadratic formula determines the number and type of answers.
The formula is b^2 -4(ac)
a = 6. b = -7 and c = -4
-7^2 -4(6*-4) = 145
The answer is a positive number so this means there are 2 real solutions.
Answer:
eY is positive +0.1 therefore bagels are a normal good.
Step-by-step explanation:
Given data:
when, 10% rise in cheese price, 3% fall in bagels quantity observed
when, 10% rise in income, 1% fall in bagels quantity observed
from formula for cross price elasticity of demand, determine 

As, eAB is negative, bagels $ cream cheese are complements.
By formula for income elasticity of demand,
we find that
Since eYis positive, bagels are a normal good.
Slope: (y2-y1)/(x2-x1)
(0,7) and (-4,7)
(7-7)/(-4-0) = 0/ -4
The slope is 0
