% means out of 100 so 1%=1/100

so 3%=3/100
$30.00=3000 cents
so you multiply 3/100 by 3000 =(3*3000)/100
you can cross out two zeros at the bottom and on the top and get
(3*30)/1 or 90/1 or 90 cents

dedylja [7]

Answer:80students

Step-by-step explanation:

Using set notation concept,

n(U) be the total number of student = 200

n(AnS') be those that earned Bachelor in Art only= 120

n(A'nS) be those that earned Bachelor in Science only= 40

n(AnS) be students that earned both degrees.

Using the formulae below to calculate n(AnS) first;

n(AuS)=n(A'nS)+ n(AnS)+n(AnS')

200=40+n(AnS)+120

200=160+n(AnS)

n(AnS)=40

This shows that 40students earned bachelor in both degrees

Those that earned Bachelor in science degree will then be n(A'nS)+n(AnS) i.e 40+40 =80students.

NB: A' means complement of A(A not included)

'n' denote intersection and 'u' denote union.
