Answer: Hello mate!
we know that p(x,y) means "Student x has taken class y"
and the used symbols are:
∃: this means "existence", you use this symbol to say that there exists at least one object that makes true the sentence.
∀: this means "for all", you use this symbol to say that the sentence is true for all the elements, then:
a) ∃x∃yP (x, y)
"exist at least one student x, that took at least one class y"
b) ∃x∀yP (x, y)
"exist at least one student x, that took all the classes y"
c) ∀x∃yP (x, y)
"every student x, took at least one class y"
d) ∃y∀xP (x, y)
"exist at least one class y, that has been taken by all the students x"
e) ∀y∃xP (x, y)
"for every class y, there is at least one student x that took the class"
f) ∀x∀yP (x, y)
"all the students x took all the classes y"
To answer this question, we first have to set up an equation with variables.
We can use "x" to represent the cost of each bracelet.
Equation: number of bracelets bought × cost of each bracelet = total cost
Number of bracelets bought: 7
Total Cost: 49
Using this information, we can fill in the equation and solve for x.
7x = 49
To isolate x, divide both sides by 7.
x = 7
Since x equals 7, we now know that each bracelet cost $7.
