Answer:
a) r ^ ¬q
b) p ^ꓥqꓥ^ r
c) r → p
d) p ^ ¬qꓥ^ r
e) (p ^ q) → r
f) r ↔ (q v p)
Step-by-step explanation:
ꓥ^ = AND Conjunction
vꓦ = OR disjunction
¬ = NOT Negation
↔ = Double Implication
→ = implication
Step-by-step explanation:
1 pound = 16 ounces
5 pound = 16 x 5 = 80
Cost per ounce = 15
Cost of 80 ounces = 15 x 80 = 1200
Option D is the correct answer
(1) x represents the number of apples bought, y represents the number of bananas.
(2) each term represents the total costs of a given fruit, so 0.50x is the total cost of apples and 0.30y is total cost of bananas.
(3) The coefficients are unit prices: coefficient 0.50 is the price of 1 apple, 0.30 is the price of 1 banana.
They must sell 250 cameras
and 50 more cameras would be a $400 profit
Add 8π to both sides of the equation to get:


We have found that x = 9π. Remember that in solving problems like these with pi that it can often be helpful to treat pi as a variable.
