P(B|A)=\dfrac{P(A \cap B)}{P(A)}\\\\ |\Omega|=20\cdot19=380\\ |A|=5\cdot19=95\\ |A\cap B|=5\cdot4=20\\\\ P(A)=\dfrac{95}{380}=\dfrac{1}{4}\\ P(A \cap B)=\dfrac{20}{380}=\dfrac{1}{19}\\\\ P(B|A)=\dfrac{\dfrac{1}{19}}{\dfrac{1}{4}}=\dfrac{1}{19}\cdot4=\dfrac{4}{19}\Rightarrow B

A bank charges $0.25 per check and its monthly fees are $10. If Jerome issues 10 checks in a month, how much will a monthly chec
blsea [12.9K]
For this case, the first thing we must do is define variables.
 We have then:
 x: number of checks.
 y: total cost.
 We now write the linear function that represents the problem.
 We have then:
 y = 0.25x + 10&#10;
 Then, Jerome issues 10 checks in a month.
 Therefore, we evaluate the function for x = 10.
 We have then:
 y = 0.25 (10) + 10&#10;&#10;y = 2.5 + 10&#10;&#10;y = 12.5
 Answer:
 
a monthly checking account will cost him about:
 
y = 12.5 $
